The DPMS Complete Upper in 5.56 NATO (brand part no. DP51655131212) is a 10.5-inch-barreled upper receiver assembly finished in black, giving builders a compact top end for an AR pistol or registered short-barreled rifle project. DPMS has built AR-pattern rifles and components for decades, and this upper drops onto a standard AR-15 lower with the usual two takedown pins. The 10.5-inch barrel length keeps the platform maneuverable for close work while retaining enough velocity for reliable 5.56 performance at practical distances.

• The barrel measures 10.5 inches, sized for compact pistol and SBR builds.

Frequently Asked Questions

Is a 10.5-inch upper legal to buy? Yes, an upper by itself is not a regulated firearm. Install it on a pistol lower or a registered short-barreled rifle; putting it on a rifle-configured lower first requires an approved ATF Form 1.

Will it fit my AR-15 lower? Yes, it attaches to any standard mil-spec AR-15 lower receiver using the front and rear takedown pins.
