The DPMS DR-15 in 5.56 NATO (brand part no. DP51655120178) is a semi-automatic AR-15 built around a 16-inch 4150V chrome-moly-vanadium barrel with a phosphate finish, giving shooters a mil-spec-pattern rifle at an accessible price. DPMS pairs the barrel with a 1-in-7-inch twist rate and a carbine-length gas system with a low-profile .750-inch gas block, builds the rifle on forged 7075-T6 aluminum upper and lower receivers with an M4 flat-top and feed ramps, and mounts a 13.5-inch PSA lightweight M-LOK free-float rail. A 6-position collapsible PSA Classic Carbine stock, a manual safety, and an included 30-round magazine round out the build. Among AR-platform rifles in the AR rifles category, the DR-15 favors shooters who want a mil-spec-pattern 5.56 AR with a free-float rail.
