The DPMS DP51655109558 is a forged AR upper with a 16" M4 profile barrel chambered in 5.56 NATO. The barrel is 4150V chrome moly vanadium steel with a nitride coating, and it carries an M4 barrel extension and a standard handguard. A carbine-length gas system runs the action, and an A2 flash hider finishes the muzzle. The upper itself is forged 7075-T6 aluminum, machined to mil-spec dimensions and hard coat anodized, and it is made in the USA.

The bolt carrier group and charging handle are part of the package, so you get the core moving parts along with the upper. The Carpenter No. 158 steel bolt is shot peened, pressure tested and magnetic-particle inspected, and its gas key is hardened to USGI spec and held with staked Grade 8 screws so the key stays secured to the carrier. A DPMS carbine drop-in handguard with heat shields covers the barrel, and the included rear MBUS sight gives you a rear sight on the upper.
