David Herman Kale, Jr., pled guilty to one count of conspiracy to defraud the United States, in violation of 18 U.S.C. § 371 (2000), one count of obstructing and delaying commerce by robbing a gas station and aiding and abetting such conduct in violation of 18 U.S.C. §§ 1951, 2 (2000), one count of using and brandishing a fire *193 arm during a crime of violence, in violation of 18 U.S.C.A. § 924(c) (West 2000 & Supp. 2007), and possession of a firearm by a convicted felon, in violation of 18 U.S.C. § 922(g)(1) (2000). With respect to the § 924(c) conviction, the district court found Kale intentionally fired the firearm at the pursuing officer which makes him eligible for a mandatory minimum ten year sentence. On appeal, Kale argues the court’s finding was clearly erroneous. Finding no error, we affirm. *

The district court’s factual findings at sentencing are reviewed for clear error. United States v. Hudson, 272 F.3d 260, 263 (4th Cir. 2001). In order to disturb a court’s factual findings, this court must be “left with definite and firm conviction that mistake has been committed.” United States v. May, 359 F.3d 683, 688 (4th Cir. 2004). A court may properly make factual findings concerning sentencing factors by a preponderance of the evidence. United States v. Morris, 429 F.3d 65, 72 (4th Cir. 2005), cert. denied, — U.S. -, 127 S.Ct. 121, 166 L.Ed.2d 91 (2006). We find the district court did not clearly err in its factual findings.

Accordingly, we affirm the convictions and sentence. 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.

AFFIRMED.
