    SUMMARY**
    Criminal Law
    The panel affirmed a conviction for one count of
    distribution of methamphetamine (Count 6) and the sentence
    imposed for five counts of distribution of methamphetamine,
    one count of distribution of cocaine, and one count of
    conspiracy to distribute.
    The panel held that there was sufficient evidence to
    support the conviction on Count 6, as to which the jury was
    instructed on an aiding and abetting theory of liability. The
    panel explained that a rational jury could have found that the
    defendant and his brother collaborated on the drug transaction
    at issue, considering all of the evidence, including the
    conspiracy and the fact that the defendant and his brother
    collaborated on multiple drug transactions in person and by
    phone.
    The panel found deeply troubling the conduct of the
    involved law enforcement agencies, but held that the
    improprieties do not warrant reversal of the district court’s
    denial of a downward departure for sentencing manipulation.
    The panel held that it was reasonable for law enforcement to
    extend the investigation to build a stronger case with more
    controlled purchases by a more credible confidential source,
    and that the existence of an ambiguous FBI memo did not
    require the district court to conclude that the investigators

    extended the investigation solely to enhance the defendant’s
    sentence.
    The panel found it was not an abuse of discretion for the
    district court to find the defendant’s criminal history to be
    accurately stated, and held that the district court did not err in
    applying an enhancement for firearm possession. The panel
    rejected the defendant’s argument that the drug quantity
    attributed to him was unforeseeable.
    Because the defendant may move the district court for
    relief under Sentencing Guidelines Amendment 782, the
    panel declined to remand the case on those grounds.

    OPINION
    LYNN, District Judge:
    This appeal arises from a series of controlled drug
    purchases conducted over a period of nearly seven months
    during 2006 and 2007.
    At trial, the defendant, Anthony Boykin (“Boykin”), was
    convicted on five counts of distribution of methamphetamine,
    one count of distribution of cocaine, and one count of
    conspiracy to distribute.       His appeal challenges the
    sufficiency of the evidence on Count Six, one of the counts
    for distribution of methamphetamine. He also challenges his
    sentence, arguing that the district court erred in (1) not
    departing downward for sentencing manipulation; (2) not
    finding his criminal history to be overstated; and (3) not
    sustaining objections to certain sentencing enhancements.
    The Court finds the evidence was sufficient to convict
    Boykin on Count Six. While the Court finds deeply troubling
    the conduct of the involved law enforcement agencies, the
    improprieties do not warrant reversal due to sentencing
    manipulation. Finally, the Court finds it was not an abuse of
    discretion for the district court to find the defendant’s
    criminal history to be accurately stated, nor for it to apply the
    enhancements challenged. Therefore, we affirm the district
    court’s rulings on each of the grounds raised on appeal.
    UNITED STATES V. BOYKIN                             5
    FACTUAL AND PROCEDURAL BAGKROUND
    I. The Controlled Purchases
    Boykin and his brother, Patrick, sold methamphetamine
    and cocaine to three different confidential sources from
    August 29, 2006 to March 26, 2007. These controlled
    purchases usually took place at 251 Wilbur Avenue, or at a
    nearby store, Wilbur Market.1 The investigation of the
    Boykins was conducted by a Narcotics Enforcement Team,
    NET-5, which was composed of local and state law
    enforcement representatives and supervised by the California
    Department of Justice, Bureau of Narcotic Enforcement.
    NET-5 also worked with federal law enforcement agencies,
    including the FBI.
    On August 29, 2006, the government directed a
    confidential source, Rachel Rios, to call Boykin to purchase
    two ounces of methamphetamine. Boykin instructed Rios to
    go to an apartment complex, where she met with an
    unidentified female while he watched the transaction from a
    second-story window. The government later deactivated Rios
    as a source when it discovered that she was still selling
    methamphetamine, and as a result, the government recruited
    a new confidential source, Crystal Housley.2
    1
    The Boykins and others in the neighborhood would frequently “hang
    out” and congregate at 251 Wilbur Avenue, a residence owned by the
    Boykins’ mother.
    2
    The record is inconsistent with respect to the spelling of Housley’s
    name. Because the trial transcript spells her name as “Housley,” the Court
    will do the same.
    6                   UNITED STATES V. BOYKIN
    Housley participated in two controlled purchases
    involving Boykin, on September 13, 2006, and September 28,
    2006. In the first purchase, Housley called Boykin and asked
    to purchase cocaine. He directed her to meet with Patrick,
    who completed the transaction. In the second purchase,
    Housley called Boykin and asked to buy methamphetamine.
    Boykin met her at Wilbur Market and completed the
    transaction.
    On or about October 27, 2006, Housley was arrested on
    federal fraud charges. However, she was not deactivated as
    a source until December 23, 2006, after she pled guilty to
    fraud. Housley had been handled by Detective Thomas
    Oakes, a narcotics detective with the Yuba County Sheriff’s
    Department and a member of NET-5, with whom she had a
    close relationship. At Boykin’s trial, Detective Oakes
    testified that upon learning of Housley’s pending federal
    fraud charges, he immediately delivered her to federal agents,
    deactivated her as an informant, and paid no further monies
    to her after she was arrested. This testimony was inaccurate,
    and ultimately led to a stipulation that, in fact, Housley
    continued to work as an informant for almost two months
    after her arrest, and she was paid during that time period.
    Detective Oakes’ brother, Jonathan “Johnny” Oakes, was
    a friend or associate of the Boykins. Johnny was known to
    “hang out and be in contact” with them, and Detective Oakes
    testified that Johnny and Boykin played pool together.3
    3
    The details of the relationship between Johnny Oakes and the Boykins
    is not entirely clear from the record, but the testimony of Detective Oakes
    prompted Judge Shubb to remark, “I thought only in the movies did police
    officers investigate cases where their brothers were personal friends of the
    person they were investigating.” Judge Shubb found the relationship so
    UNITED STATES V. BOYKIN                              7
    Despite the conflict arising from the relationship of Johnny to
    the Boykins, Detective Oakes continued to participate in the
    investigation, although the extent of his participation was
    disputed.4
    After Housley was deactivated, the government recruited
    a third confidential source, Robert Walton, who conducted
    controlled purchases from the Boykins on February 3, 2007,
    February 9, 2007, March 16, 2007, and March 26, 2007.
    Boykin often facilitated the transaction over the phone, or he
    directly passed the drugs to Patrick, who delivered them to
    Walton.
    On appeal, Boykin challenges the sufficiency of the
    evidence only for the drug transaction of February 9, 2007.
    Patrick arranged for that transaction to take place at 251
    Wilbur Avenue. Both brothers were outside the residence
    when Walton arrived. Walton left with Patrick to pick up a
    scale and met an unidentified Hispanic male at Wilbur
    Market to obtain the drugs, after which they returned to 251
    Wilbur Avenue. Walton remained in Patrick’s truck while
    Patrick went in the house. Boykin had also left 251 Wilbur
    “remarkable” that he thought it would be wrong to not let the jury hear
    about Johnny Oakes’ relationship with the Boykins.
    4
    Detective Oakes testified that his brother’s relationship with the
    Boykins prompted his supervisors to limit his involvement in the
    investigation by assigning him to manage informant Housley. Detective
    Oakes acknowledged that he was present for the two drug transactions
    with Housley. He could not recall whether he was present or part of the
    surveillance team for transactions involving Walton. Detective Oakes
    described his role in the case as “very limited,” which the Court construes
    to mean that his role was more limited than at least some other members
    of NET-5 working on the Boykin case.
    8                UNITED STATES V. BOYKIN
    Avenue, but he returned after Patrick and Walton did. An
    unidentified white male also entered the residence while
    Walton sat in Patrick’s truck.           Officers conducting
    surveillance testified that Patrick made several trips in and
    out of 251 Wilbur Avenue before completing the transaction
    with Walton. The government also introduced evidence that
    several phone calls were made between Patrick and Boykin
    during the relevant time period. The evidence showed that
    Patrick began arranging for the drug transaction at 11:58 a.m.,
    and it took place at 2:11 p.m. Meanwhile, Boykin called
    Patrick at 12:35 p.m., and Patrick called Boykin at 1:51 p.m.
    and 3:04 p.m.
    On March 29, 2007, law enforcement officials executed
    search warrants at 251 Wilbur Avenue, Patrick’s residence,
    and Boykin’s residence. At Boykin’s residence, agents seized
    $27,000 in cash, scales with drug residue, and cellular
    telephones used during the controlled purchases. At 251
    Wilbur Avenue, agents found a small amount of
    methamphetamine with packaging material, two scales, and
    several guns, including a sawed-off shotgun with Boykin’s
    fingerprints.
    II. Proceedings in the District Court
    Boykin and Patrick were charged by indictment with one
    count of conspiracy to distribute and possess with intent to
    distribute methamphetamine and cocaine, in violation of
    21 U.S.C. §§ 846 and 841(a)(1); six counts of distribution of
    methamphetamine, in violation of 21 U.S.C. § 841(a)(1); and
    one count of distribution of cocaine, in violation of 21 U.S.C.
    § 841(a)(1). Patrick pled guilty to the conspiracy count, but
    Boykin proceeded to a jury trial. On March 4, 2011, the jury
    returned its verdict, finding Boykin guilty of the conspiracy
    UNITED STATES V. BOYKIN                     9
    count and six counts of distribution, and acquitting him of
    one count of distribution of methamphetamine.
    The Presentence Report (PSR) recommended a base
    offense level of 34, plus a two-level increase under United
    States Sentencing Guidelines (“U.S.S.G.”) § 2D1.1(b)(1) for
    possession of a firearm, resulting in an Adjusted Offense
    Level of 36. The PSR recommended 262 months of
    incarceration, which was at the low end of the advisory
    guideline range, after taking into account Boykin’s criminal
    history level of IV.
    The district court gave Boykin a two-level reduction for
    acceptance of responsibility, which placed the Adjusted
    Offense Level at 34. Finding that Boykin’s criminal history
    was accurately stated in the PSR, the court concluded that the
    guideline range was 210 to 262 months, and sentenced
    Boykin to 210 months to avoid any sentencing disparity with
    Patrick, who also received a sentence of 210 months.
    Boykin filed a timely notice of appeal, challenging the
    sufficiency of the evidence on Count Six and arguing that the
    district court erred by not granting a downward departure for
    sentencing manipulation, and by not finding his criminal
    history to be overstated. After initial briefing was complete,
    Boykin filed a pro se supplemental brief, arguing the district
    court committed plain error by applying a two-level
    enhancement for possession of a firearm, and by failing to
    conduct an individualized analysis of his participation in the
    conspiracy. On September 24, 2014, Boykin’s counsel sent
    a letter to the Court, requesting remand in light of
    Amendment 782 to the U.S. Sentencing Guidelines.
    10               UNITED STATES V. BOYKIN
    ANALYSIS
    I. Sufficiency of the Evidence
    The court reviews de novo a challenge to the sufficiency
    of the evidence. United States v. Antonakeas, 
    255 F.3d 714
    ,
    723 (9th Cir. 2001). “Viewing the evidence in the light most
    favorable to the government, [the Court] must determine
    whether any rational jury could have found [the defendant]
    guilty of each element of the crime beyond a reasonable
    doubt.” United States v. Esquivel-Ortega, 
    484 F.3d 1221
    ,
    1224 (9th Cir. 2007) (citation omitted). The trier of fact has
    the responsibility “to resolve conflicts in the testimony, to
    weigh the evidence, and to draw reasonable inferences from
    basic facts to ultimate facts.” Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979).
    A conviction for possession with intent to distribute may
    be based on one of three legal theories: (1) co-conspirator
    liability; (2) aiding and abetting; and (3) exercising dominion
    and control over the contraband. United States v. Sanchez-
    Mata, 
    925 F.2d 1166
    , 1168 (9th Cir. 1991) (citations
    omitted).
    Boykin argues the government failed to establish that he
    actually or constructively possessed the methamphetamine on
    February 9, 2007. However, because the jury was instructed
    on an aiding and abetting theory of liability, it was not
    necessary for the government to show actual or constructive
    possession, or that Boykin actually sold the drugs. See
    United States v. Gillock, 
    886 F.2d 220
    , 222 (9th Cir. 1989).
    Rather, it was enough to show that Boykin associated with
    the criminal venture, participated in it, and sought, by his
    actions, to make it a success. See 
    id. Circumstantial evidence
                        UNITED STATES V. BOYKIN                           11
    may support a conviction for aiding and abetting. United
    States v. Corona-Verbera, 
    509 F.3d 1105
    , 1119 (9th Cir.
    2007).
    Here, there was sufficient evidence for a rational jury to
    find that Boykin aided and abetted Patrick’s distribution of
    methamphetamine on February 9, 2007. Patrick arranged the
    transaction and told Walton to come to 251 Wilbur Avenue.
    Both Patrick and Boykin were there when Walton arrived.
    After leaving briefly, Patrick and Walton returned to 251
    Wilbur Avenue. Boykin, who had also left, returned to 251
    Wilbur Avenue as Patrick was making trips back and forth
    between the residence and Patrick’s truck, where Walton
    remained and where the drug transaction ultimately took
    place. The government’s evidence also showed three phone
    calls between Boykin and Patrick on February 9, 2007, two
    of which were close in time to the transaction.5 Finally, law
    enforcement found drug paraphernalia, guns, and money
    when they executed search warrants at Boykin’s residence
    and 251 Wilbur Avenue. See 
    Gillock, 886 F.2d at 222
    (holding an intent to distribute could be inferred from the gun
    found in the defendant’s closet and the large quantities of lab
    5
    Boykin correctly notes that the first call was from Boykin to Patrick.
    However, the second call was from Patrick to Boykin. The Court is bound
    to respect that the jury has “exclusive province . . . to . . . resolve
    evidentiary conflicts, and draw reasonable inferences from proven facts.”
    See 
    Gillock, 886 F.2d at 222
    . This rule applies to these calls, and also
    applies to Boykin’s argument that either the unidentified white male who
    entered the residence around the same time he did, or the unidentified
    Hispanic male with whom Patrick and Walton met at Wilbur Market,
    could have supplied the methamphetamine. Those facts were for the jury
    to decide, and even if construed as the defendant contends, they do not
    necessarily mean Boykin did not aid and abet the transaction.
    12               UNITED STATES V. BOYKIN
    equipment and methamphetamine found in the residences of
    the defendant’s associates).
    Considering all of the evidence, including the conspiracy
    and the fact that Boykin and Patrick collaborated on multiple
    drug transactions, in person and by phone, a rational jury
    could have found that Boykin and Patrick collaborated on the
    drug transaction of February 9, 2007. See United States v.
    Smith, 
    832 F.2d 1167
    , 1172 (9th Cir. 1987) (“Hence, this is
    not a case involving nothing more than a simple, isolated
    purchase.”). For the aforementioned reasons, we affirm the
    jury’s conviction on the February 9, 2007 count for
    distribution of methamphetamine.
    II. Sentencing
    A. Sentencing Manipulation
    The Ninth Circuit has not always been careful in
    recognizing the distinction between “sentencing entrapment”
    and “sentencing manipulation.” See, e.g., United States v. Si,
    
    343 F.3d 1116
    , 1128 (9th Cir. 2003) (“the result of sentencing
    factor manipulation, also known as sentencing entrapment”);
    United States v. Riewe, 
    165 F.3d 727
    , 729 (9th Cir. 1999);
    United States v. Staufer, 
    38 F.3d 1103
    , 1106 (9th Cir. 1994)
    (describing “sentencing entrapment” as “sentence factor
    manipulation”). When a defendant can show he was
    predisposed to commit a minor or lesser offense, but was
    entrapped to commit a greater offense, subject to greater
    punishment, he may be eligible for a downward departure or
    variance for “sentencing entrapment.” United States v. Mejia,
    
    559 F.3d 1113
    , 1118 (9th Cir. 2009). In contrast, “sentencing
    manipulation” occurs when the government increases a
    defendant’s guideline sentence by conducting a lengthy
    UNITED STATES V. BOYKIN                     13
    investigation which increases the number of drug transactions
    and quantities for which the defendant is responsible. United
    States v. Torres, 
    563 F.3d 731
    , 734 (8th Cir. 2009). In other
    words, what sets “sentencing entrapment” apart from
    “sentencing manipulation” is that, in the latter, “the judicial
    gaze should, in the usual case, focus primarily—though not
    necessarily exclusively—on the government’s conduct and
    motives.” United States v. Fontes, 
    415 F.3d 174
    , 181–82 (1st
    Cir. 2005).
    To prove sentencing manipulation, a defendant must show
    “that the officers engaged in the later drug transactions solely
    to enhance his potential sentence.” 
    Torres, 563 F.3d at 734
    .
    Cases from other circuits have granted relief for sentencing
    manipulation in “only the extreme and unusual case”
    involving “outrageous governmental conduct.” See 
    Fontes, 415 F.3d at 180
    ; United States v. Beltran, 
    571 F.3d 1013
    ,
    1018–19 (10th Cir. 2009) (explaining that, based on due
    process principles, sentencing manipulation “allow[s] a court
    to modify a sentence if considering the totality of the
    circumstances, ‘the government’s conduct is so shocking,
    outrageous and intolerable that it offends ‘the universal sense
    of justice’’”). If a court finds sentencing manipulation, a
    downward departure should be applied to the guidelines
    range, “since such manipulation artificially inflates the
    offense level by increasing the quantity of drugs included in
    the relevant conduct.” 
    Torres, 563 F.3d at 734
    –35.
    Although Boykin argued below that his sentence should
    be reduced due to sentencing entrapment, the substance of his
    argument and the district court’s analysis indicate that Boykin
    mislabeled the argument. In fact, Boykin’s challenge
    addressed the conduct of law enforcement rather than his
    predisposition. Given the thrust of Boykin’s argument and
    14               UNITED STATES V. BOYKIN
    the lack of precision with which we have previously used the
    terms “sentencing entrapment” and “sentencing
    manipulation,” we review the district court’s factual findings
    in the sentencing phase for clear error. See United States v.
    Castaneda, 
    94 F.3d 592
    , 594 (9th Cir. 1996). “In order to
    reverse a district court’s factual findings as clearly erroneous,
    we must determine that the district court’s factual findings
    were illogical, implausible, or without support in the record.”
    United States v. Spangle, 
    626 F.3d 488
    , 497 (9th Cir. 2010).
    To support his sentencing manipulation argument, Boykin
    points to three facts that allegedly motivated law enforcement
    to induce further controlled purchases from the Boykins:
    (1) the FBI memo reviewing the progress of the investigation
    against Patrick, Boykin, and others, and explaining that
    additional drug buys would be necessary to reach the
    sentencing goals set by the U.S. Attorney’s Office;
    (2) Detective Oakes’ close relationship with confidential
    source Housley; and (3) the close relationship of Detective
    Oakes’ brother, Johnny, to Boykin and Patrick. Boykin
    argues that Detective Oakes’ participation in the investigation
    constitutes outrageous government conduct, which supports
    a finding of sentencing manipulation under a test employed
    by the Tenth Circuit. See 
    Beltran, 571 F.3d at 1017
    –18. In
    the alternative, Boykin argues that he was entitled to a
    downward departure because law enforcement engaged in
    additional transactions solely to increase his sentence, urging
    us to follow precedent from the Eighth Circuit. See 
    Torres, 563 F.3d at 734
    .
    Regardless of the test employed, Boykin fails to
    demonstrate that the district court’s findings were clearly
    erroneous. With regard to the test in Beltran, although the
    Court is deeply troubled by the participation of Detective
    UNITED STATES V. BOYKIN                           15
    Oakes, the investigation fell just shy of constituting
    outrageous government conduct. As a result of his unusually
    close relationship with informant Housley and his brother’s
    friendship with the Boykins, Oakes clearly had multiple
    incentives to prolong the investigation.6 Furthering this
    perception, Oakes gave erroneous testimony at trial regarding
    his response to learning of Housley’s arrest on fraud charges,
    requiring a stipulation at trial between the parties that Oakes
    in fact continued working with, and paying, Housley after the
    arrest. However, despite Oakes’ conflict of interest, because
    his role was limited and he was being supervised, rather than
    directing the investigation, his conduct was “wrong and
    troubling,” but not so “extreme and outrageous” as to warrant
    a downward departure for sentencing manipulation. See
    
    Fontes, 415 F.3d at 183
    .7
    With respect to the Torres test, Boykin asks the Court to
    hold that it is improper for the government to continue an
    6
    Boykin also notes that Detective Oakes arranged for NET-5 to pay for
    Housley’s apartment and utilities. Detective Oakes also gave her his
    home phone number, which he admitted was unusual. However, NET-5
    apparently had a meeting to approve these payments, and Detective Oakes
    testified that agents kept a close eye on Housley because NET-5 paid for
    her apartment.

    The investigation of the Boykins was not an operation “created and
    staged” by law enforcement, nor was law enforcement “trolling for
    targets” based on economic and social conditions in the community. See
    United States v. Black, 
    733 F.3d 294
    , 303 (9th Cir. 2013). Rather, in
    investigating the Boykins, law enforcement was infiltrating a preexisting
    criminal organization. See 
    id. at 302.
    (“It is not outrageous . . . to
    approach individuals who are already involved in or contemplating a
    criminal act, or to provide necessary items to a conspiracy.”). Therefore,
    the due process concerns raised and rejected in Black are not implicated
    in this case.
    16               UNITED STATES V. BOYKIN
    investigation merely to enhance the defendant’s sentence, and
    that mitigating a defendant’s sentence is a fitting tool to deter
    such improper investigations. This Court has previously held
    that a district court may consider the full amount of drugs
    involved when law enforcement arranges multiple controlled
    drug purchases for legitimate investigatory reasons. United
    States v. Baker, 
    63 F.3d 1478
    , 1500 (9th Cir. 1995). Thus,
    the issue here is whether legitimate reasons existed for the
    investigation or whether it was solely intended to increase
    Boykin’s sentence.
    In Baker, this Court rejected the defendant’s argument
    that his conviction should be reversed because the
    government stretched out its investigation to increase the
    drug quantity and potential charges against the defendant
    after it had sufficient evidence to indict. 
    Id. The Court
    “decline[d] to adopt a rule that, in effect, would find
    ‘sentencing manipulation’ whenever the government, even
    though it has enough evidence to indict, opts instead to wait
    in favor of continuing its investigation” because “[s]uch a
    rule ‘would unnecessarily and unfairly restrict the discretion
    and judgment of investigators and prosecutors,’” and
    “[p]olice . . . must be given leeway to probe the depth and
    extent of a criminal enterprise, to determine whether
    coconspirators exist, and to trace . . . deeper into the
    distribution hierarchy.” 
    Id. (internal quotations
    and citations
    omitted). Finally, the Court emphasized that because “the
    government bears the burden of proving its case beyond a
    reasonable doubt, it must be permitted to exercise its own
    judgment in determining at what point in an investigation
    enough evidence has been obtained.” 
    Id. Here, there
    was evidence that the government extended its
    investigation to build a stronger case against Boykin. Of
    UNITED STATES V. BOYKIN                      17
    particular concern was that the government’s first two
    confidential sources—Rios and Housley—were both
    convicted of serious offenses during the period they were
    acting as confidential sources against the Boykins. Therefore,
    it was reasonable for law enforcement to extend the
    investigation with more controlled purchases by a more
    credible confidential source. This is precisely what law
    enforcement did in having Walton make controlled purchases
    in February and March 2007.
    Further, the existence of the FBI memo did not require the
    district court to conclude that the investigators extended the
    investigation solely to enhance Boykin’s potential sentence.
    Although the memo specifically recommended drug volumes
    to establish charges, its text is too ambiguous to establish that
    the agents’ sole intent was to enhance Boykin’s sentence,
    because it discusses several defendants earlier in the text and
    the phrase in question does not clearly refer to Boykin:
    Additional drug buys from several of the
    captioned subjects will be necessary to reach
    the preferred thresholds established by the
    United States Attorney’s Office in the Eastern
    District of California. It is recommended by
    their office that 50 grams or more of
    methamphetamine or 500 grams or more of a
    cocaine powder be purchased from one
    individual to secure a five (5) year mandatory
    minimum sentence. This case continues.
    In fact, on January 31, 2007, when the memo was
    circulated, Boykin had already participated in controlled
    purchases involving over 50 grams of methamphetamine,
    which was the amount described in the memo as necessary to
    18                UNITED STATES V. BOYKIN
    meet the five-year statutory mandatory minimum sentence.8
    Thus, the district court did not clearly err by not finding the
    FBI memo to be a basis for a charge of sentencing
    manipulation.
    B. Criminal History
    Boykin also argues the district court erred by failing to
    look at the underlying facts of his criminal history when
    deciding if it was overstated.
    The Court reviews de novo a district court’s interpretation
    of sentencing guidelines, and the application of the
    sentencing guidelines is reviewed for abuse of discretion.
    United States v. Hernandez-Guerrero, 
    633 F.3d 933
    , 935 (9th
    Cir. 2011). “A sentencing court is permitted under U.S.S.G.
    § 4A1.3 to depart from a recommended sentence if it believes
    that a defendant’s criminal history category significantly
    over-represents the seriousness of his criminal record or the
    likelihood that he will commit further crimes.” United States
    v. Govan, 
    152 F.3d 1088
    , 1094 (9th Cir. 1998). Furthermore,
    the district court retains discretion to depart downward from
    the guidelines should it find “mitigating circumstances of a
    kind, or to a degree, not adequately taken into consideration
    by the Sentencing Commission in formulating the guidelines
    that should result in a sentence different from that described.”
    United States v. Brown, 
    985 F.2d 478
    , 481 (9th Cir. 1993)
    8
    On August 29, 2006, Boykin distributed two ounces of
    methamphetamine. On September 13, 2006, Boykin distributed one-
    eighth of an ounce of cocaine. On September 28, 2006, Boykin
    distributed eight ounces of methamphetamine. One ounce is equal to
    approximately 28.35 grams, which means Boykin had met the 50 gram
    threshold well before the FBI memo was circulated.
    UNITED STATES V. BOYKIN                    19
    (quoting 18 U.S.C. § 3553(b)) (alteration omitted). The
    district court may consider “without limitation, any
    information concerning the background, character and
    conduct of the defendant, unless otherwise prohibited [by the
    guidelines or other law].” 
    Id. (citing U.S.S.G.
    § 1B1.4).
    At the sentencing hearing, Boykin gave a detailed
    explanation of the facts and circumstances surrounding his
    convictions for vandalism and a loud noise disturbance, and
    argued that the facts underlying those offenses were not
    sufficiently egregious to warrant two additional points being
    counted toward his criminal history category. The district
    court responded that “you get on a slippery slope when you
    start trying to look at the underlying facts and look beyond
    the judgment in determining the criminal history,” and stated
    that the “criminal history [was] calculated properly,” and that
    it did not “believe that the criminal-history category
    [overstated] the seriousness of the criminal history.” This
    ruling was not an abuse of discretion, and the trial court was
    not required to give a further explanation.
    Boykin further objects to the addition of two criminal
    history points for a 2001 misdemeanor conviction for
    disturbance of the peace, which Boykin argues was part of a
    plea deal in which the prosecutor found that the domestic
    abuse victim’s allegations were not credible. He also objects
    to the addition of one point for a 2005 misdemeanor
    conviction for vandalism, in which Boykin arrived at a
    burning apartment allegedly believing his children were
    inside, discovered his children were fine, and then became
    obstructive when officers allegedly treated him
    contemptuously.
    20               UNITED STATES V. BOYKIN
    It was not an abuse of discretion for the court to
    determine these incidents were properly calculated in
    determining Boykin’s criminal history.
    C. Weapon and Coconspirator Enhancements
    Finally, Boykin argues that the district court erred by
    applying a two-level enhancement for firearm possession.
    This Court reviews for clear error the district court’s factual
    determination that the firearm enhancement in U.S.S.G.
    § 2D1.1(b)(1) applies. United States v. Kelso, 
    942 F.2d 680
    ,
    681 (9th Cir. 1991).
    The defendant argues the district court never connected
    him to the handgun. However, Boykin misinterprets both the
    enhancement and his burden. The two-level sentencing
    adjustment is appropriate “unless it is clearly improbable that
    the weapon was connected with the offense.” U.S.S.G.
    § 2D1.1 n. 3 (2010). The government “must prove
    possession by a preponderance of the evidence before the
    court can apply the two-level increase under § 2D1.1(b)(1).”
    United States v. Cazares, 
    121 F.3d 1241
    , 1244 (9th Cir. 1997)
    (quoting United States v. Mergerson, 
    4 F.3d 337
    , 350 (5th
    Cir. 1993)).
    This Court has defined “possession” broadly. United
    States v. Pitts, 
    6 F.3d 1366
    , 1372 (9th Cir. 1993). “To
    demonstrate constructive possession the government must
    prove ‘a sufficient connection between the defendant and the
    contraband to support the inference that the defendant
    exercised dominion and control over the [contraband].’”
    
    Kelso, 942 F.2d at 682
    (quoting United States v. Disla,
    
    805 F.2d 1340
    , 1350 (9th Cir. 1986)). Where a defendant is
    convicted of conspiracy, the firearm enhancement can be
    UNITED STATES V. BOYKIN                         21
    based on all of the offense conduct, not just the crime of
    conviction. United States v. Willard, 
    919 F.2d 606
    , 610 (9th
    Cir. 1990), cert. denied, 
    502 U.S. 872
    (1991).
    Here, agents recovered several firearms from the
    residence at 251 Wilbur Avenue, including a sawed-off
    shotgun with Boykin’s fingerprints. The evidence showed
    Boykin engaged in numerous drug transactions at 251 Wilbur
    Avenue. Thus, the court did not clearly err by finding Boykin
    possessed a weapon connected with the offense. See 
    Pitts, 6 F.3d at 1372
    .
    Boykin also argues the district court failed to make a
    proper individualized assessment of his relevant conduct in
    the conspiracy. He argues his tenuous connection with the
    transaction of February 9, 2007 made that drug quantity
    unforeseeable to him.
    For reasons already discussed, the evidence was sufficient
    to convict Boykin of aiding and abetting the transaction of
    February 9, 2007. Therefore, the drug quantity attributed to
    him was foreseeable. See 
    Willard, 919 F.2d at 610
    .
    For the foregoing reasons, we affirm the sentence
    imposed by the district court.9
    AFFIRMED.
    9
    Because Boykin may move the district court for relief under
    Amendment 782 to the Guidelines, the Court declines to remand the case
    on those grounds. See 18 U.S.C. § 3582(c)(2).
