DPMS DR15 Features The DPMS DR15 is built around a chrome-moly vanadium steel barrel finished in nitride for corrosion resistance chambered in 5.56 NATO with a 1:7 twist rate to stabilize heavier match and hunting bullet weights. A mid-length gas system and M4 barrel extension provide smooth reliable cycling across a range of ammunition types while the 13.5 inch M-Lok free-float handguard allows for a wide range of accessory mounting without contacting the barrel. The full-auto profile bolt carrier group uses a shot-peened Carpenter 158 steel bolt hardened and staked to mil-spec for long-term durability under repeated firing. A forged 7075-T6 A3 upper receiver machined to mil-spec and hard coat anodized rounds out a rifle built on genuine mil-spec manufacturing standards right here in the USA. The forged 7075-T6 lower receiver carries a hard-coat anodized finish and is fitted with a mil-spec diameter buffer tube offering six positions of adjustment. B5 Systems furniture includes the Bravo stock premium grip and trigger guard working together with the Panther Polished Trigger for a smooth consistent trigger pull shot after shot. A Picatinny top rail provides a reliable mounting surface for optics while the threaded 1/2x28 muzzle accepts the A2-style flash hider or an aftermarket muzzle device. At 6.8 lbs this rifle balances well and remains easy to carry and maneuver making it a strong all-around choice for range use home defense or further customization.
