    *   Of the Federal Circuit, sitting by designation.
    BARRON, Circuit Judge.    In connection with a 2015 scheme
    to transport cocaine from the Dominican Republic to Puerto Rico,
    José Antonio Hernández-Hernández ("Hernández") pleaded guilty to,
    and was convicted of, two drug-trafficking offenses and two money-
    laundering offenses in the United States District Court for the
    District of Puerto Rico.     Hernández now challenges his sentence.
    We affirm.
    I.
    Hernández was indicted in 2015 on four counts of an
    eight-count indictment that also charged three others -- Kelvin
    Radhames De Morla-Santana ("De Morla"), Dima Osiris Gerardino-
    Manzueta ("Gerardino"), and José Luis Hernández-Peña -- for their
    respective roles in the drug-trafficking scheme.        Unbeknownst to
    the conspirators, the individuals on the other side of the planned
    transaction to bring the cocaine to Puerto Rico and distribute it
    included federal law enforcement agents.
    More specifically, the indictment charged Hernández with
    one count of conspiracy to possess with intent to distribute five
    kilograms or more of cocaine in violation of 21 U.S.C. §§ 846,
    841(a)(1) and (b)(1)(A)(ii); one count of attempted possession
    with intent to distribute controlled substances in violation of 21
    U.S.C. §§ 841(a)(1), (b)(1)(A)(ii), 18 U.S.C. § 2; and two counts
    - 2 -
    of money laundering in violation of 18 U.S.C. §§ 1956(a)(1)(A)(i),
    2.
    The government offered Hernández a plea deal.   If he
    would plead guilty to the first drug-trafficking count and both of
    the money-laundering counts, then the government would agree to
    the following in return.     First, the government would stipulate
    that Hernández was only accountable for offenses involving at least
    15 kilograms of cocaine but less than 50 kilograms, even though
    the conspirators initially agreed to transport 200 kilograms of
    cocaine to Puerto Rico and actually delivered roughly 60 kilograms
    of cocaine.    That stipulation would have had favorable sentencing
    consequences for Hernández under the United States Sentencing
    Guidelines ("Guidelines") due to the base offense level that
    corresponds to that stipulated drug quantity. See U.S.S.G. § 2D1.1
    (U.S. Sentencing Comm'n 2018) (providing a base offense level of
    32 for drug-trafficking offenses involving "[a]t least 15 KG but
    less than 50 KG of Cocaine"; a base offense level of 34 for drug-
    trafficking offenses involving "[a]t least 50 KG but less than 150
    KG of Cocaine"; and a base offense level of 36 for drug-trafficking
    offenses involving "[a]t least 150 KG but less than 450 KG of
    Cocaine").
    Second, the government would agree not to pursue a
    sentencing enhancement under the Guidelines pursuant to U.S.S.G.
    § 2D1.1(b)(1), based on firearms that had been seized from his
    - 3 -
    codefendants.        That    guideline,      which    requires    a   two-level
    enhancement,    applies      when   "a    dangerous    weapon    (including   a
    firearm) was possessed" in relation to the defendant's offense if
    it involved drugs.
    Id. Under this
    proposed deal, all three counts would have
    been grouped for Guidelines calculation purposes.                 See U.S.S.G.
    § 3D1.2(c) (explaining that counts should be grouped "[w]hen one
    of the counts embodies conduct that is treated as a specific
    offense characteristic in, or other adjustment to, the guideline
    applicable to another of the counts").                Thus, his base offense
    level under the Guidelines would have been 32.                    See U.S.S.G.
    § 2D1.1.
    The government anticipated, moreover, that Hernández's
    total offense level under this deal would have been 33.                That was
    so   because   the   government      intended    to    request    a   two-level
    enhancement under U.S.S.G. § 3B1.1, which allows for an increase
    of two or four levels for a "leader" or "organizer" of "a criminal
    activity" depending on whether that activity was "extensive"; a
    two-level enhancement pursuant to U.S.S.G. § 2S1.1(b)(2)(B), which
    imposes a two-level increase for a defendant who was also convicted
    of a money-laundering offense pursuant to 18 U.S.C. § 1956; and a
    three-level     reduction     for   his    acceptance     of     responsibility
    pursuant to U.S.S.G. § 3E1.1(a)-(b).
    - 4 -
    If Hernández had accepted this plea deal, given his
    expected total offense level of 33 and his criminal history
    category     of    I,     his   recommended       sentencing      range,    per    the
    Guidelines,       would    have    been    135-168    months     of    imprisonment.
    Hernández, however, rejected the plea deal.               He would not agree to
    the application of the sentencing enhancement for being a leader
    or organizer of criminal activity under U.S.S.G. § 3B1.1.                              He
    instead entered a straight plea of guilty to each of the four
    counts for which he had been charged in the indictment.
    The    United        States     Probation    Office        prepared        a
    presentence report ("PSR") based on Hernández's straight guilty
    plea.    Hernández filed various objections to it.
    First, Hernández objected to the sentencing enhancement
    of four levels that the PSR applied for his role as a leader or
    organizer     of    an    extensive       criminal    activity     under    U.S.S.G.
    § 3B1.1(a).        See U.S.S.G. § 3B1.1(a) ("If the defendant was an
    organizer or leader of a criminal activity that involved five or
    more    participants       or   was   otherwise      extensive,       increase    by    4
    levels.").
    Second, Hernández objected to the two-level enhancement
    under U.S.S.G. § 2D1.1(b)(1) that the PSR applied based on the
    firearms seized from his codefendants.                 He argued that only his
    codefendants had been in possession of the firearms on which the
    - 5 -
    enhancement was premised and that he could not have foreseen his
    codefendants' possession of them.
    Finally, Hernández disputed the PSR's finding that his
    drug-trafficking offenses involved 200 kilograms of cocaine and
    thus that his base offense level was 36.          He argued that, even
    though the venture was originally set to transport that amount of
    cocaine, the offenses only involved the 60 kilograms of cocaine
    that were actually delivered, which meant that his base offense
    level should be 34.       See U.S.S.G. § 2D1.1(c) (providing a base
    offense level of 34 for offenses involving between 50-150 kilograms
    of cocaine, and a base offense level of 36 for offenses involving
    150-450 kilograms of cocaine).
    The Probation Office amended the PSR to find Hernández
    responsible for 60 kilograms of cocaine rather than 200 kilograms.
    The amended PSR thus, after grouping all four counts pursuant to
    U.S.S.G. § 3D1.2(c), calculated his base offense level to be 34,
    see U.S.S.G. § 2D1.1(c)(3).
    The amended PSR then applied a four-level enhancement
    for Hernández's role as a leader or organizer, pursuant to U.S.S.G.
    § 3B1.1(a),   as   well   as   an   enhancement   pursuant   to   U.S.S.G.
    § 2D1.1(b)(15)(C).1   The latter guideline provides for a two-level
    1 Although the Sentencing Guidelines in effect when the
    amended PSR was prepared in 2016 listed this enhancement under
    § 2D1.1(b)(15)(C), in the Guidelines in effect at Hernández's
    - 6 -
    enhancement when a defendant "receives an adjustment under §3B1.1"
    and "the defendant was directly involved in the importation of a
    controlled substance."
    Id. The application
    of each of those
    enhancements brought Hernández's total offense level to 40.
    The amended PSR also applied two more enhancements.                        It
    applied    the     two-level        enhancement      pursuant        to      U.S.S.G.
    § 2D1.1(b)(1),     in    connection    with    Hernández's         coconspirators'
    firearms possession.         It then applied the two-level enhancement
    pursuant to U.S.S.G. § 2S1.1(b)(2)(B), because of Hernández's
    money-laundering        convictions    under    18    U.S.C.       § 1956.          The
    application of these two additional enhancements brought his total
    offense level to 44.
    The     amended     PSR,     however,      also        made     one      more
    adjustment -- this time to Hernández's benefit.                      It applied a
    three-level      reduction    for     his    acceptance      of     responsibility
    pursuant to U.S.S.G. § 3E1.1(a)-(b).
    That adjustment reduced his total offense level to 41.
    His criminal history category was I.                 The result was that the
    amended PSR's recommended guideline sentencing range was 324-405
    months of imprisonment.
    After receiving the amended PSR, Hernández objected
    again.    He challenged the application of the leader or organizer
    sentencing in 2019,          that     same    enhancement      is        provided     at
    § 2D1.1(b)(16)(C).
    - 7 -
    enhancement,    U.S.S.G.       § 3B1.1(a),     arguing     that   instead    of     an
    enhancement     he     deserved    a   two-level     reduction      pursuant        to
    § 3B1.2(b) because his role was only that of a "minor" participant.
    He also challenged the dangerous weapon enhancement under U.S.S.G.
    § 2D1.1(b)(1).       Hernández additionally requested that he be given
    a two-level safety-valve reduction pursuant to U.S.S.G. § 5C1.2,
    which mitigates the harsh effect of mandatory minimum sentences on
    certain first-time offenders who played only supporting roles in
    drug-trafficking schemes and who provided testimony about their
    involvement in the criminal activity.            See United States v. Ortiz-
    Santiago, 
    211 F.3d 146
    , 150–51 (1st Cir. 2000).
    The government, for its part, disputed the amended PSR's
    drug quantity determination.           It argued that Hernández's sentence
    should be based on a base offense level that reflected the entire
    200 kilograms of cocaine that he originally promised to traffic
    rather than only the 60 kilograms that were delivered.
    The District Court accepted the defendant's guilty plea.
    With respect to sentencing, the District Court initially followed
    the government's recommendation and found that the drug quantity
    was   200   kilograms     of   cocaine   rather     than    the   amended        PSR's
    recommended 60 kilograms.          Accordingly, the District Court found
    that Hernández had a base offense level of 36 rather than 34, as
    the   amended    PSR     had   determined      it   to     be.      See   U.S.S.G.
    § 2D1.1(c)(2)        (providing    a   base    offense      level    of     36     for
    - 8 -
    drug-trafficking offenses involving "[a]t least 150 KG but less
    than 450 KG of Cocaine").        The District Court then followed the
    amended PSR, however, by applying the same sentencing enhancements
    and reductions that it had recommended.
    The District Court found that the four-level enhancement
    pursuant to U.S.S.G. § 3B1.1(a) for a leader or organizer applied
    because the defendant was an "organizer" and "the criminal activity
    involved five or more participants, and also . . . was extensive."
    That finding, in turn, along with other reasons, caused the
    District Court to reject Hernández's request for a safety-valve
    reduction of two levels.        But, that finding also resulted in the
    District Court applying the two-level enhancement set forth in
    U.S.S.G.   § 2D1.1(b)(16)(C),      which    calls   for   those    additional
    levels to be added to a defendant's offense level when § 3B1.1(a)
    applies and the offense involves the importation of controlled
    substances.
    With the total offense level then at 42, the District
    Court applied two additional two-level enhancements.              One was the
    weapons enhancement pursuant to U.S.S.G. § 2D1.1(b)(1), and the
    other was the enhancement pursuant to U.S.S.G. § 2S1.1(b)(2)(B),
    which   was    based   on   Hernández's    money-laundering   convictions.
    Those enhancements brought the total offense level to 46.
    Finally, the District Court applied the three-level
    reduction for acceptance of responsibility pursuant to U.S.S.G.
    - 9 -
    § 3E1.1(a)-(b).   That adjustment resulted in a total offense level
    of 43 rather than 41, which the amended PSR had calculated it to
    be.
    With this total offense level, and a criminal history
    category of I, Hernández's recommended guideline sentencing range
    was, the District Court noted, life imprisonment.              But, the
    District Court decided to apply a two-level downward variance by
    "assuming" for sentencing purposes (notwithstanding its earlier
    factual finding that the drug quantity involved in the drug
    trafficking offenses was 200 and not merely 60 kilograms of
    cocaine) that, consistent with the amended PSR's calculation,
    Hernández's drug-trafficking offenses only involved "at least 50
    kilos, but less than 150 kilos of cocaine," which would bring
    Hernández's   base   offense   level   down   to   34.   See   U.S.S.G.
    § 2D1.1(c)(3).
    Thus, after grouping Hernández's counts of conviction
    pursuant to § 3D1.2(c), the District Court applied Hernández's
    sentencing enhancements to the base offense level of 34, resulting
    in a total offense level of 41.     Hernández's resulting Guidelines
    sentencing range was 324-405 months of imprisonment, which is the
    range for a person with that total offense level and a criminal
    history category of I.         The District Court then applied the
    § 3553(a) sentencing factors and sentenced Hernández to 324 months
    of imprisonment for the drug-trafficking counts and 240 months of
    - 10 -
    imprisonment    for   the   money-laundering   counts,   to   be   served
    concurrently.
    Hernández timely appealed his sentence.
    II.
    We start with Hernández's contention that the District
    Court committed procedural errors in calculating his Guidelines
    sentencing range.     The alleged errors concern the application of
    the various enhancements to which he had objected below, as well
    as the District Court's refusal to apply one of the downward
    adjustments that he had requested. Because Hernández was sentenced
    in 2019, we apply the Guidelines in effect at that time, which
    were the 2018 Guidelines.      See United States v. Crudup, 
    375 F.3d 5
    , 8 (1st Cir. 2004) ("Normally, the sentencing judge is to apply
    the guidelines version in effect at the time of sentencing.").        We
    find no merit to these challenges.
    A.
    Hernández first challenges the four-level "leader or
    organizer" enhancement that the District Court applied pursuant to
    U.S.S.G § 3B1.1(a).    This enhancement requires a district court to
    make "both a status determination -- a finding that the defendant
    acted as an organizer or leader of the criminal activity -- and a
    scope determination -- a finding that the criminal activity met
    either the numerosity or the extensiveness benchmarks established
    - 11 -
    by the guideline."         United States v. Tejada-Beltran, 
    50 F.3d 105
    ,
    111 (1st Cir. 1995).
    The District Court found that Hernández satisfied the
    status requirement based on a finding that he was an "organizer."
    The District Court also found that the scope requirement was met
    because     "the     criminal       activity     involved    five       or   more
    participants."
    On   appeal,     Hernández    does    not   contest   the   District
    Court's scope finding.          Thus, the only question for us concerns
    Hernández's      status:      was   he   an    "organizer"   of   the   criminal
    activity?
    To qualify as an "organizer," "the defendant must have
    exercised some degree of control over others involved in the
    commission of the offense or he must have been responsible for
    organizing others for the purpose of carrying out the crime."
    United States v. Carrero-Hernández, 
    643 F.3d 344
    , 350 (1st Cir.
    2011) (quoting United States v. Fuller, 
    897 F.2d 1217
    , 1220 (1st
    Cir. 1990)).        Specifically, the defendant "must have been the
    organizer" not only of the general activity but also "of one or
    more other participants" who were not "undercover law enforcement
    officer[s]."       U.S.S.G. § 3B1.1(a) cmts. nn.1-2; see United States
    v. Arbour, 
    559 F.3d 50
    , 56 (1st Cir. 2009) ("[T]he guideline
    commentary makes plain that a defendant needs only to have led or
    organized one criminal participant, besides himself of course, to
    - 12 -
    qualify as a leader or organizer under § 3B1.1(a)."). Importantly,
    "our cases distinguish between organizing criminal activities and
    organizing criminal actors.       Only the latter may be used to ground
    an enhancement under § 3B1.1(a)."        
    Carrero-Hernández, 643 F.3d at 350
    –51 (footnote omitted).
    As    we   will   explain,   the   District   Court   found   that
    Hernández, in the course of facilitating various aspects of the
    drug-trafficking scheme, gave significant "instructions" to at
    least one of his codefendants to help ensure the transfer within
    Puerto Rico of what he thought was cocaine (although, by that time,
    the undercover law enforcement agents had ensured that it was
    actually fake).       We review that factual finding for clear error,
    see United States v. Walker, 
    665 F.3d 212
    , 232 (1st Cir. 2011),
    and we conclude that the District Court did not clearly err in
    making it, see United States v. Belanger, 
    890 F.3d 13
    , 36 (1st
    Cir. 2018) ("Clear error cannot be said to exist unless 'on the
    entire evidence [we are] left with the definite and firm conviction
    that a mistake has been committed.'" (alteration in original)
    (quoting United States v. Brown, 
    298 F.3d 120
    , 122 (1st Cir.
    2002))); see also United States v. Ruiz, 
    905 F.2d 499
    , 508 (1st
    Cir. 1990) ("[W]here there is more than one plausible view of the
    circumstances, the sentencing court's choice among supportable
    alternatives cannot be clearly erroneous.").              For that reason,
    although   the   evidence    of   Hernández's   general   coordination    of
    - 13 -
    criminal activities is not itself enough to show that he was an
    "organizer," the entire record evidence suffices to show that the
    District Court did not err in finding that he was.
    The District Court did not specify the "instructions"
    that it had in mind in finding that Hernández gave them.                  In its
    brief   to    us,    though,    the     government     asserts     that    these
    "instructions"      included    Hernández's    direction      to   one    of   his
    codefendants (and thus not an undercover agent) to drive the car
    that was supposed to contain the cocaine that had been brought to
    Puerto Rico so that it could be transferred to facilitate its
    distribution.
    Hernández does not dispute the government on this point.
    Thus, the key question for us is whether the record suffices to
    support the District Court's finding that Hernández gave that key
    instruction to a codefendant to facilitate the venture.                        We
    conclude that it does.
    It is undisputed that Hernández thought that he was
    coordinating the sea-transfer of cocaine to an individual who went
    by the name "Looney Tunes," who would then bring the cocaine into
    the   Commonwealth,     where    it    would   be    picked   up   for    future
    distribution.    Unbeknownst to Hernández, however, Looney Tunes was
    in fact not a single individual but a group of undercover Homeland
    Security Investigations ("HSI") agents.             According to the record,
    Hernández's     communications     with    Looney     Tunes   throughout       the
    - 14 -
    venture were extensive.   They concerned both the coordination of
    the initial transfer of what was then real cocaine at sea from
    Hernández's associates to Looney Tunes so that it could be brought
    to Puerto Rico, as well as the planned transfer of it (though, by
    then the undercover agents had swapped in sham cocaine) within the
    Commonwealth   from   Looney   Tunes     back   to   Hernández's   other
    associates.2   It was in the course of carrying out that second
    planned transfer of the cocaine that, the record supportably shows,
    Hernández gave the "instruction" that provides the sufficient
    basis for the District Court's "organizer" finding.
    After   Hernández    reached    out   to   Looney   Tunes   to
    coordinate the transfer in Puerto Rico of what he thought was real
    cocaine for cash, the record shows, Looney Tunes told Hernández
    that the exchange would happen at the Pep Boys Auto Store at
    Altamira in Guaynabo, Puerto Rico.        At the appointed time, the
    record further shows, Hernández and his codefendant, José Luis
    2The record shows that Hernández had many communications with
    Looney Tunes via BlackBerry messenger.       These communications
    included the coordination of the sea transfer of cocaine from
    Hernández's associates, who arrived in a boat coming from the
    Dominican Republic, to Looney Tunes, who came in a boat from Puerto
    Rico. The record also shows that these communications resulted in
    an agreement as to the amount of money that Hernández would pay
    Looney Tunes for fuel expenses during the transfer at sea. And,
    the record shows that when Hernández's associates who were aboard
    their vessel from the Dominican Republic transferred only
    approximately 60 kilograms of cocaine to Looney Tunes rather than
    the promised 200 kilograms, it was Hernández who messaged with
    Looney Tunes to sort out the disparity.

    Hernández-Peña, arrived in a Honda and parked at the Pep Boys Auto
    Store, while another codefendant, Gerardino, arrived in a Mazda.
    At that point, the record reveals, an HSI undercover
    agent whom Hernández thought was Looney Tunes told him that the
    exchange spot to transfer the cocaine was being moved to the Tren
    Urbano Martinez Nadal Station parking lot in Guaynabo.   The record
    shows that the following then transpired:      Hernández exited the
    Honda and got into the Mazda, which Gerardino was driving, and the
    two men, together, then left the Pep Boys Auto Store parking lot
    in the Mazda and drove to the Tren Urbano Martinez Nadal Station
    parking lot.
    According to the record, the HSI agent posing as Looney
    Tunes informed Hernández -- exactly when is not clear -- that the
    cocaine was inside a Ford Expedition that was parked at the
    Martinez Nadal Station parking lot and that he should retrieve the
    keys from the Ford and drive away in it.   Significantly, the record
    as presented on appeal does not indicate that the instruction from
    the undercover agent to Hernández to get in the Ford and drive
    away in it gave as an option that Hernández should instruct
    Gerardino to do so in his stead.   Nevertheless, the record shows,
    after the agent had transmitted this instruction to Hernández about
    getting into the Ford, it was Gerardino and not Hernández who got
    out of the Mazda, entered the Ford that had the sham cocaine, and
    then attempted to drive away in it.
    - 16 -
    Thus, the record permits the inference that Hernández
    had instructed Gerardino to get into the Ford that contained the
    sham cocaine and drive away in it and that Hernández had done so
    on his own initiative rather than at another's direction.                To be
    sure,    there   is   no   direct   evidence   that   Hernández   gave    this
    instruction directing a coconspirator to carry out this critical
    aspect of the venture or that in doing so he exercised his own
    discretion.      But, the inference that he chose to give that key
    instruction at that critical moment on his own initiative draws
    strength not only from the discrete sequence of events just
    described concerning what happened in Puerto Rico but also from
    the District Court's amply supported finding that Hernández "had
    a complete understanding of the totality of the activity, before
    and after," of the venture as a whole and thus that he was not
    merely a bit player operating at its margins.
    In disputing that the record supportably shows that
    Hernández gave this instruction, Hernández does not contest that
    he was instructed by the agents to drive the Ford that had the
    sham cocaine or that, in the end, Gerardino was the one driving
    it.     He even admits that "[t]he agents instructed [him] to take
    the Ford pick-up parked at the train station which had the drugs
    inside and to leave the car in which he arrived with the money
    - 17 -
    inside."3    But, he contends, the sworn statement from Gerardino
    that he rather than Hernández was "following the instructions of
    another individual" when he rather than Hernández "went to exchange
    the red Mazda for another vehicle" shows that, contrary to the
    District    Court's     finding,   Hernández    did    not   "control[]"    or
    "exercise[] decision-making authority" over his coconspirator in
    that instance.
    We may assume to Hernández's benefit that Gerardino's
    statement is best read to imply that the "another individual" to
    whom he referred was not Hernández.            But, even if we make that
    assumption, we still conclude that the District Court did not
    clearly err in finding as it did as to Hernández giving this
    instruction.
    The District Court could reasonably have disregarded
    such a statement from Gerardino as not credible.             United States v.
    Appolon, 
    695 F.3d 44
    , 66 (1st Cir. 2012) ("[W]here there is more
    than one plausible view of the circumstances, the sentencing
    court's choice among supportable alternatives cannot be clearly
    erroneous.").       After all, Hernández fails to point to any evidence
    in   the   record    that   indicates   that   the    "individual"   to   whom
    3Hernández also said the agents "directed [Hernández] to a
    van parked at the train station and gave him instructions to
    retrieve the car keys from the van's fueling area and drive away
    in the van and to leave the Mazda CX-7 with the money in the
    parking lot."
    - 18 -
    Gerardino referred was anyone but Hernández, as nothing in the
    record indicates that Gerardino was in contact at that time with
    anyone other than Hernández.              By contrast, the evidence does show
    that   Hernández      was    the    contact       for    Looney     Tunes      and     had
    communicated directly with him at the key moment about getting
    into the Ford and driving it away.
    We   therefore        conclude       that     the     record      evidence
    supportably shows that Hernández, acting on his own initiative,
    instructed    Gerardino      "to    exchange      the    red     Mazda   for    another
    vehicle" and thus that the District Court did not clearly err in
    finding that Hernández "gave instructions."                    Accordingly, because
    the District Court supportably found that Hernández instructed a
    coconspirator (and not an undercover agent) to perform this key
    task in this criminal venture, we agree with the government that
    the District Court committed no error in applying the four-level
    sentencing enhancement pursuant to U.S.S.G. § 3B1.1(a), based on
    a finding that Hernández was an "organizer."
    B.
    Hernández next argues that the District Court erred in
    adding an additional two-level enhancement pursuant to U.S.S.G.
    § 2D1.1(b)(16).        That enhancement states:                  "If the defendant
    receives an adjustment under § 3B1.1 (Aggravating Role) and the
    offense   involved     1     or    more    of    the    following    factors         . . .
    [including    that]    the    defendant         was    directly   involved      in     the
    - 19 -
    importation of a controlled substance . . . [then] increase by 2
    levels."   We have just explained, though, that the District Court
    did not err in applying the § 3B1.1 enhancement due to Hernández's
    status as an organizer.      Thus, this challenge fails, as Hernández
    does not challenge the application of this enhancement on any other
    ground.
    C.
    Hernández also challenges the District Court's refusal
    to apply the so-called safety-valve reduction, which would reduce
    his total offense level by two levels if it were applicable.                     See
    U.S.S.G.   § 5C1.2;     18   U.S.C.     § 3553(f).          A   prerequisite      to
    eligibility for the safety-valve reduction, however, is that "the
    defendant was not an organizer, leader, manager, or supervisor of
    others in the offense."         U.S.S.G. § 5C1.2(a)(4).              Because the
    District   Court      supportably     found        that     Hernández      was    an
    "organizer," he is not eligible for this reduction.                   Thus, this
    challenge also fails.
    D.
    That brings us to Hernández's challenge to the two-level
    enhancement    that    the   District      Court    imposed      under     U.S.S.G.
    § 2D1.1(b)(1), which applies "[i]f a dangerous weapon (including
    a   firearm)   was    possessed."     We     review       the   District   Court's
    interpretation and application of the Guidelines de novo, and its
    - 20 -
    factual findings for clear error.     See United States v. Nuñez, 
    840 F.3d 1
    , 4 (1st Cir. 2016).
    This enhancement "is applicable whether the weapon is
    possessed     by   the   defendant   himself    or   by   one    of   his
    coconspirators."     United States v. Gobbi, 
    471 F.3d 302
    , 313 (1st
    Cir. 2006).    Hernández does not dispute that although he was not
    found to be in possession of a weapon himself, his codefendants,
    Gerardino and De Morla, arrived at the location of the drug
    transfer with weapons in their vehicles.       He argues, however, that
    because he was unaware that his codefendants possessed firearms,
    the District Court erred in applying the enhancement.           We do not
    agree.
    So long as it is "reasonably foreseeable that a co-
    conspirator would possess a weapon in furtherance of the criminal
    activity," a defendant need not actually be aware of the existence
    of his coconspirator's weapon for the enhancement to apply. United
    States v. Greig, 
    717 F.3d 212
    , 219 (1st Cir. 2013).        In addition,
    as we have explained before, "[a]bsent evidence of exceptional
    circumstances, we think it fairly inferable that a codefendant's
    possession of a dangerous weapon is foreseeable to a defendant
    with reason to believe that their collaborative criminal venture
    includes an exchange of controlled substances for a large amount
    of cash."     United States v. Bianco, 
    922 F.2d 910
    , 912 (1st Cir.
    1991); see also United States v. Miranda-Martinez, 
    790 F.3d 270
    ,
    - 21 -
    276 (1st Cir. 2015) (explaining that "firearms are common tools"
    in drug-trafficking schemes (quoting 
    Bianco, 922 F.2d at 912
    )).
    Moreover, once it has been shown that a coconspirator possessed a
    firearm during an offense and that it was reasonably foreseeable
    to the defendant for the coconspirator to do so, "[t]he enhancement
    should be applied . . . unless it is clearly improbable that the
    weapon was connected with the offense."           U.S.S.G. § 2D1.1(b)(1)
    cmt. n.11(A).
    The District Court did not clearly err in determining
    that at least one of Hernández's "[co]conspirators possessed a
    weapon during the offense" and that "it was foreseeable to have
    that weapon present during the exchange" because "[t]his was a
    very dangerous situation dealing with [and] involving significant
    amount[s] of drugs and money."       In fact, far from pointing to any
    such exceptional circumstances here that could compel a different
    conclusion than the one the District Court reached on that score,
    Hernández admitted the situation was "extremely dangerous" because
    the individuals on the other side of the drug-trafficking scheme
    were "dangerous."      Nor can Hernández show that he had met his
    burden to demonstrate that it was "clearly improbable" that the
    weapons involved were related to the drug-trafficking scheme, see
    United   States   v.   Anderson,   
    452 F.3d 87
    ,   91   (1st   Cir.   2006)
    (explaining that "once the government shows that the firearm was
    present during the commission of the offense," the defendant must
    - 22 -
    meet the "heav[y] burden . . . of establishing that it was clearly
    improbable that the gun was used in connection with the offense"),
    as his bare assertion that he was unaware that his codefendants
    were carrying firearms is not sufficient to do so.                    See U.S.S.G.
    § 2D1.1(b)(1) cmt. n.11(A).             Thus, the District Court committed no
    error in applying this sentencing enhancement.                    See 
    Greig, 717 F.3d at 219
    .
    E.
    Hernández's final procedural challenge to his sentence
    is that the District Court erred in initially finding that his
    drug-trafficking offenses involved 200 kilograms of cocaine.                      We
    agree with the government, however, that any error was harmless.
    The   District      Court,    as   we    have   explained,     ultimately    varied
    downward by sentencing him as if the offenses involved only 60
    kilograms of cocaine.         The District Court thus imposed Hernández's
    sentence     as    if   the    base      offense     level     that   he    contends
    applies -- 34 rather than 36 -- did apply.                   Nor does the record
    indicate that the District Court would have varied downward even
    more if it had initially found that Hernández's drug-trafficking
    offenses     involved    60    kilograms        of   cocaine    rather     than   200
    kilograms.        See Williams v. United States, 
    503 U.S. 193
    , 202–03
    - 23 -
    (1992) (explaining that if "the district court would have imposed
    the same sentence" even without the error, it was harmless).
    III.
    Hernández's final challenge to his sentence is that it
    is substantively unreasonable under 18 U.S.C. § 3553(a)(6), which
    directs district courts "to avoid unwarranted sentence disparities
    among defendants with similar records who have been found guilty
    of similar conduct."        Hernández bases his argument on the fact
    that his 324-month prison sentence for his drug-trafficking crimes
    is   significantly      longer    than      the   prison      sentences     of   his
    codefendants,    Gerardino       and   De   Morla.         They   were   sentenced,
    respectively, to 123 months and 120 months of imprisonment, while
    Hernández was sentenced to 324 months.
    We   review    preserved        challenges      to    the    substantive
    reasonableness of a sentence for abuse of discretion.                    See United
    States v. Viloria-Sepulveda, 
    921 F.3d 5
    , 8 (1st Cir. 2019).                      "A
    sentence is substantively reasonable so long as it rests on a
    plausible sentencing rationale and embodies a defensible result."
    United States v. Ruiz-Huertas, 
    792 F.3d 223
    , 228 (1st Cir. 2015)
    (internal quotation marks omitted).
    Section 3553(a)(6) warns against disparate sentences for
    similarly    situated     codefendants,         but   "a    district     court   may
    consider differences and similarities between co-defendants at
    sentencing."     United States v. Marceau, 
    554 F.3d 24
    , 33 (1st Cir.
    - 24 -
    2009).    In this case, Hernández was both convicted of offenses
    that his codefendants were not and declined to enter into a plea
    agreement   while   his   codefendants   did.   In   light   of   these
    differences between Hernández and his codefendants, we must reject
    his disparity challenge.
    IV.
    For the reasons stated, we affirm Hernández's sentence.
