      Mauricio Arevalo-Magana pled guilty to being an unlawful alien in possession

of firearms and ammunition. See 18 U.S.C. §§ 922(g)(5)(A), 924(a)(2). He now

appeals his 33-month sentence, claiming the district court assigned an incorrect base

        After examining the briefs and appellate record, this panel has determined
unanimously to honor the parties’ request for a decision on the briefs without oral
argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore
submitted without oral argument. This order and judgment is not binding precedent,
except under the doctrines of law of the case, res judicata, and collateral estoppel. It
may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1
and 10th Cir. R. 32.1.
                                I.   BACKGROUND

      During an investigation of Tim Sumner for stealing 47 firearms from an

Oklahoma home, undercover agents with the Bureau of Alcohol, Tobacco, and

Firearms (ATF) attempted to purchase the weapons from him. Police eventually

seized 42 of the 47 firearms. Mr. Sumner said he sold the remaining guns—including

a Bushmaster .223 caliber semiautomatic rifle and a Rock River Arms .223 caliber

rifle—to Mr. Arevalo-Magana in exchange for marijuana and $500.1 The two rifles

and three other firearms were never recovered.

      Through their investigation, ATF agents learned that Mr. Arevalo-Magana

stayed in the apartment of Remi Carrillo. Mr. Carrillo told an unnamed ATF agent

that Mr. Arevalo-Magana showed him photos of “AR-15 type rifles” that he had

purchased. R. at 28. He said Mr. Arevalo-Magana disposed of the firearms after

learning that Mr. Sumner had told the police he had sold the firearms to Mr. Arevalo-

Magana.

      A grand jury indicted Mr. Arevalo-Magana on three counts: (1) being an

unlawful alien in possession of firearms and ammunition, including the Bushmaster

and Rock River Arms rifles, 18 U.S.C. §§ 922(g)(5)(A), 924(a)(2); (2) possession of

marijuana with intent to distribute, 21 U.S.C. § 841(a)(1), (b)(1)(D); and

(3) possession of firearms in furtherance of a drug trafficking crime, 18 U.S.C.



      1
        Mr. Sumner said he sold the weapons to an individual named “Wicho,” Supp.
R., Vol. II at 14, which is one of Mr. Arevalo-Magana’s aliases.

                                         -2-
§ 924(c)(1)(A)(i). He pled guilty to count one in exchange for dismissal of counts

two and three. He preserved his right to appeal any contested sentencing issue.

          Under the plea agreement, the parties stipulated for sentencing purposes that

the anticipated base offense level would be 20 under the U.S. Sentencing Guidelines

Manual § 2K2.1(a)(4)(B) (U.S. Sentencing Comm’n 2015). That provision applies if

the offense involved a semiautomatic firearm capable of accepting a large-capacity

magazine.2 Mr. Arevalo-Magana admitted to possessing the firearms charged in

count one of the indictment, including the Bushmaster and the Rock River Arms

rifles.

          The presentence investigation report (PSR) did not apply § 2K2.1(a)(4)(B).

Instead, the PSR assigned a lower base offense level of 14 under USSG

§ 2K2.1(a)(6), without regard to whether the offense involved a semiautomatic

firearm capable of accepting large-capacity magazines. The government objected,

arguing that the Bushmaster and Rock River Arms rifles were semiautomatic firearms

capable of accepting large-capacity magazines. The government claimed that when

ATF agents attempted to purchase the firearms from Mr. Sumner, he sent them

photos depicting the rifles with large-capacity magazines attached. The government

also asserted the burglary victim told ATF Agent Carlos Sandoval he had 20- and

30-round magazines for these rifles.



          2
        Section 2K2.1(a)(4)(B) also requires the defendant to be a “prohibited
person.” Mr. Arevalo-Magana does not dispute his status as a prohibited person.

                                            -3-
      At sentencing, the parties stipulated that the rifles were stolen in new

condition, in their original boxes, with large-capacity magazines. See Supp. R.,

Vol. II at 11-12, 21-22. Also, the government called ATF Agent Lucas Keck. He

testified that he had conducted a phone interview of Mr. Sumner, who said the

“AR-style rifles” “were brand new . . . in the factory-style boxes[] when he []

received them and sold them” to Mr. Arevalo-Magana. Id. at 15. He told Agent

Keck the magazines “were in the original boxes with the rifles” and, although he was

unfamiliar with the magazines, he knew “they were the same ones that came from the

factory.” Id. Agent Keck added that the factory magazines “would have been 20- or

30-round magazines.” Id. at 21.

      The district court sustained the government’s objection, ruling there was

sufficient evidence to find that Mr. Arevalo-Magana possessed semiautomatic rifles

with large-capacity magazines in close proximity. The court therefore applied the

base offense level of 20 under § 2K2.1(a)(4)(B). It added 2 levels for the number of

guns involved, another 2 because they were stolen, and 4 more because they were

possessed in connection with another felony (the drug offense), yielding an offense

level of 28. The court then reduced the offense level by 3 because Mr. Arevalo-

Magana accepted responsibility, and granted a 6-level stipulated variance, resulting

in a final offense level of 19. Accounting for his category-I criminal history, the

court determined the applicable sentencing guideline range was 30 to 37 months. It

sentenced Mr. Arevalo-Magana to 33 months in prison.



                                          -4-
      Now on appeal, Mr. Arevalo-Magana contends there was insufficient evidence

to support the higher base offense level under § 2K2.1(a)(4)(B) because the rifles

were never recovered. He also contends the government’s evidence at sentencing

was unreliable and could not sustain the greater base offense level.

                                  II. DISCUSSION

      “Our appellate review of a defendant’s sentence includes both a procedural

component, encompassing the method by which a sentence was calculated, as well as

a substantive component, which relates to the length of the resulting sentence.”

United States v. Saavedra, 523 F.3d 1287, 1289 (10th Cir. 2008) (internal quotation

marks omitted). Mr. Arevalo-Magana contends the district court lacked sufficient or

reliable evidence that he possessed the rifles with large-capacity magazines to impose

a greater base offense level under § 2K2.1(a)(4)(B). “This is a proper procedural

argument because it challenges the district court’s method of fact-finding on a fact

that it used to increase [his] sentence.” United States v. Lente, 647 F.3d 1021, 1031

(10th Cir. 2011).

      We examine such procedural challenges for an “abuse of discretion, under

which we review de novo the district court’s legal conclusions regarding the

[G]uidelines and review its factual findings for clear error.” United States v. Gantt,

679 F.3d 1240, 1246 (10th Cir. 2012). The government bears the burden to prove by

a preponderance of the evidence that the offense involved a semiautomatic firearm

capable of accepting a large-capacity magazine. See United States v. Flonnory,

630 F.3d 1280, 1285-86 (10th Cir. 2011) (“The facts necessary to calculate the

                                         -5-
guidelines sentencing range must be proved by a preponderance of the

evidence . . . .”); United States v. Rutter, 897 F.2d 1558, 1560 (10th Cir. 1990)

(“[T]he quantum of proof required for factual determinations under the Sentencing

Guidelines is a preponderance of the evidence and the burden of proof generally is

allocated to the government for sentence increases and to the defendant for sentence

decreases.”).

      Under § 2K2.1(a)(4)(B), the applicable base offense level is 20 if the “offense

involved a [] semiautomatic firearm that is capable of accepting a large capacity

magazine.” The commentary notes of § 2K2.1 define a “semiautomatic firearm that

is capable of accepting a large capacity magazine” as:

      a semiautomatic firearm that has the ability to fire many rounds without
      reloading because at the time of the offense (A) the firearm had attached
      to it a magazine or similar device that could accept more than 15 rounds
      of ammunition; or (B) a magazine or similar device that could accept
      more than 15 rounds of ammunition was in close proximity to the
      firearm.

USSG § 2K2.1 cmt. n.2.

      It is undisputed that the Bushmaster and Rock River Arms rifles are capable of

accepting large-capacity magazines that hold more than 15 rounds. The question is

whether large-capacity magazines were attached to or within close proximity of the

rifles at the time of the offense. On this score, there was ample evidence that

Mr. Sumner sold the rifles to Mr. Arevalo-Magana with the original, large-capacity

magazines from the manufacturer. The parties stipulated that the rifles were stolen

new, in their original boxes, which contained large-capacity magazines. Mr. Sumner


                                          -6-
confirmed to Agent Keck that he sold the rifles to Mr. Arevalo-Magana with the

magazines. Mr. Arevalo-Magana admitted to possessing the rifles. And although

Mr. Sumner was unfamiliar with the capacity of the magazines, he knew they were

the factory magazines, which Agent Keck testified were capable of holding 20 or 30

rounds. Presented with this evidence, the district court did not clearly err in finding

that Mr. Arevalo-Magana possessed the semiautomatic rifles with large-capacity

magazines in close proximity.

      Mr. Arevalo-Magana contends, however, that Agent Keck’s testimony was

unreliable. He points out that Mr. Sumner was not present at the sentencing hearing

and Agent Keck merely relayed his recollection of their phone interview. But

hearsay statements may be considered at sentencing so long as they bear sufficient

indicia of reliability. See United States v. Martinez, 824 F.3d 1256, 1260 n.5

(10th Cir. 2016); United States v. Ruby, 706 F.3d 1221, 1229 (10th Cir. 2013);

see also USSG § 6A1.3(a) (“[T]he court may consider relevant information without

regard to its admissibility under the rules of evidence applicable at trial, provided that

the information has sufficient indicia of reliability to support its probable

accuracy.”).

      When hearsay is introduced at a sentencing hearing, “[c]orroborating evidence

is often key to determining whether a statement is sufficiently reliable.” Ruby,

706 F.3d at 1229. For example, in Martinez, we concluded the district court did not

clearly err in considering multi-layered hearsay statements that were supported by

corroborating evidence. 824 F.3d at 1263. The court there found that the defendant

                                          -7-
possessed a firearm in connection with another felony for purposes of applying a

four-level enhancement under USSG § 2K2.1(b)(6)(B). Id. at 1259-60. That finding

was based in part on the co-defendant’s incriminating statements to police, which

were memorialized in written police reports indicating that the defendant obtained

the firearm during a burglary they jointly committed. Id. at 1258, 1260-61. These

statements were admitted at sentencing through an ATF agent who had neither

spoken to the co-defendant nor been present during the co-defendant’s interviews

with police. Id. at 1260. We affirmed the enhancement because corroborating

evidence tended to confirm the accuracy of the co-defendant’s statements, id. at

1263;3 see also United States v. Roach, 978 F.2d 573, 575-76 (10th Cir. 1992)

(affirming enhancement based on ATF agent’s hearsay sentencing testimony that was

corroborated by other evidence).

      Here, too, corroborating evidence supported the veracity of Mr. Sumner’s

statements. Mr. Sumner said the rifles were brand new, in the original boxes, with

the factory magazines, when he sold them to Mr. Arevalo-Magana. Mr. Arevalo-

Magana admitted to possessing the rifles, and the parties stipulated that they were

stolen in new condition, with the large-capacity magazines. The burglary victim told

ATF Agent Sandoval that he had large-capacity magazines for these rifles when they

      3
         The corroborating evidence was that the co-defendant knew the defendant
would have at least one firearm from the burglary, the defendant possessed the stolen
firearm nine days after the burglary, the defendant suspiciously stated he obtained the
firearm “in a field from an unknown white guy” long before the firearm was actually
stolen, and the defendant had a lengthy record of theft offenses. Martinez, 824 F.3d
at 1262 (internal quotation marks omitted).

                                         -8-
were stolen, and Agent Keck testified without objection that the original factory

magazines would have held 20 or 30 rounds. This information refutes any suggestion

that the magazines had a lower capacity.

       Moreover, Mr. Sumner sent a photo to undercover ATF agents, which was

admitted at sentencing, depicting the rifles with their large-capacity magazines

attached, and Mr. Carrillo told an ATF agent that Mr. Arevalo-Magana showed him a

photo of AR-15-type rifles he had purchased. Although Mr. Arevalo-Magana notes

that Mr. Sumner merely “believed the weapons . . . had the original magazines with

them,” Supp. R., Vol. II at 16 (emphasis added), Mr. Arevalo-Magana stipulated that

the rifles were stolen with large-capacity magazines in the original boxes.

       The evidence corroborates Mr. Sumner’s statements and provides sufficient

indicia of reliability as to their veracity. The district court therefore did not clearly

err in considering this evidence and finding that Mr. Arevalo-Magana possessed

semiautomatic rifles with large-capacity magazines in close proximity.

                                  III. CONCLUSION

       The judgment of the district court is affirmed.
