This DPMS 11.5" 5.56 Complete Upper is built around an 11.5" barrel of 4150V chrome moly vanadium steel, chambered for 5.56 NATO and rifled with a 1:7 twist. A carbine-length gas system with a low-profile gas block runs the semi-auto action, and the barrel has an A2 profile. Because the bolt carrier group and charging handle are both included, the upper arrives as a complete assembly ready for your AR-15 pattern lower. An A2 flash hider threads onto the 1/2x28 muzzle threads at the end of the barrel.

The receiver is a forged 7075-T6 aluminum A3 upper with a hard coat anodized black finish, which gives the surface lasting durability. Inside, the bolt is shot-peened mil-spec Carpenter 158 steel in a full-auto profile carrier, and the gas key is secured with grade 8 fasteners and staked per mil-spec. Up front, the DPMS 10.5" Lightweight M-Lok handguard gives you M-Lok slots for mounting compatible accessories.
