Before MORRIS SHEPPARD ARNOLD, FAGG, and SMITH, Circuit Judges.
                         ___________

PER CURIAM.

       Tyree L. Lampkin appeals the sentence the district court1 imposed after he
pleaded guilty to conspiring to distribute and possess with intent to distribute
50 grams or more of a mixture or substance containing cocaine base, in violation of
21 U.S.C. § 846. Mr. Lampkin contests the amount of cocaine base the court
attributed to him at sentencing. See U.S.S.G. § 2D1.1(c)(1). The government bears
the burden of establishing by a preponderance of the evidence both the type and

Nebraska.
quantity of drugs attributable to a defendant, and we “will reverse only if firmly
convinced a mistake has been made.” See United States v. Thompson, 

,
784 (8th Cir. 2003) (type), cert. denied, 

(U.S. Jan. 12, 2004) (No. 03-
7643); United States v. Sarabia-Martinez, 

, 450 (8th Cir. 2002)
(quantity). After carefully reviewing the record, including the sentencing testimony
of various witnesses who described drug transactions involving Mr. Lampkin, we
conclude the district court’s findings of drug type and quantity are not clearly
erroneous. See 

; United States v. Maxwell, 

, 1397 (8th Cir.), cert. denied, 

(1994). Accordingly, we affirm.
