Affirmed by unpublished per curiam opinion.

Unpublished opinions are not binding precedent in this circuit.

William David Pope pled guilty, without a written agreement, to possession with intent to distribute methamphetamine, in violation of 21 U.S.C. § 841(a)(1), (b)(1)(B) (2012). In calculating Pope’s Sentencing Guidelines range, the presentence report included as relevant conduct methamphetamine and firearms seized from an incident for which Pope was indicted but did not plead guilty. * Over Pope’s objections, the district court adopted the PSR and sentenced him to 121 months in prison, a term at the low end of the Guidelines range. Pope now appeals, challenging the calculation of drug quantity’ under U.S. Sentencing Guidelines Manual § 2D1.1(c), Notes to Drug Quantity Table, (A) (2015), and the application of an enhancement for the possession of firearms under USSG § 2D1.1(b)(1). We affirm.

We review a district court’s legal conclusions at sentencing de novo and its factual findings for clear error. United States v. Gomez-Jimenez, 750 F.3d 370, 380 (4th Cir. 2014). “Under this clear error stan *181 dard, we will reverse the district court’s finding only if we are left with the definite and firm conviction that a mistake has been committed.” United States v. Crawford, 734 F.3d 339, 342 (4th Cir. 2013) (internal quotation marks omitted). In resolving factual disputes, a “sentencing court may give weight to any relevant information before it, ... provided that the information has sufficient indicia of reliability to support its accuracy.” Gomez-Jimenez, 750 F.3d at 380; see United States v. McDowell, 745 F.3d 115, 120 (4th Cir. 2014) (affording “considerable deference to a district court’s determinations regarding the reliability of information in a PSR”).

Upon our review of the record and the parties’ arguments, we conclude that Pope has not made a sufficient showing to’ demonstrate that the distinct court clearly erred in calculating his Guidelinés range. See Crawford, 734 F.3d at 342; United States v. Manigan, 592 F,3d 621, 626 (4th Cir. 2010). Drug quantities may be determined based on relevant conduct. USSG § 2D1.1 cmt. n.5. The evidence from the June 10 incident was sufficiently connected to the offense to which Pope pled guilty. See United States v, McVey, 752 F.3d 606, 610 (4th Cir. 2014) (identifying factors to consider when determining sufficient connection of offenses). Pope further did not meet his burden of establishing that it was clearly improbable that the firearms seized on June 10 were not connected with the offense. See United States v. Slade, 631 F.3d 185, 189 (4th Cir. . 2011) (defendant has burden of establishing clear improbability).

Accordingly, we affirm the criminal judgment. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
