Description

Small guns pack a big punch, too. This shorty AR-15 upper, chambered in .300 Blackout, is the perfect way to build the ultimate close-up hog gun or personal defense weapon. The mil-spec 4150V barrel features a phosphate coating, offering greatly improved barrel life and better accuracy than a chrome-lined barrel.

A pistol-length gas system and 1:8 twist rate provide reliable feeding and consistent shot groups with light- or heavy-grain loads. The forged M4 upper receiver provides plenty of rail estate for your favorite optic, irons, or reflex sight. This upper is test-fired and backed by a Lifetime Warranty.
