This 10.5” AR-15 barreled upper is perfect for building the ultimate medium- to close-range SBR or pistol. It features a mil-spec, 4150CMV barrel for superior accuracy. A nitride coating enhances barrel life just like chrome-lining, but it also affords greater precision than a chrome-lined barrel. An M16 BCG, 1:7 twist rate, and M4 feed ramps guarantee this upper will handle any 5.56 loads you put through it.

Out back, you’re getting a quality 7075 T6 forged upper with standard Picatinny rail. The free-float, 9” M-Lok handguard offers plenty of rail estate for your favorite irons and accessories. This upper ships preassembled, test-fired, and ready for the range with a Lifetime Warranty.
