Description

Sometimes, the smallest pistol with the most firepower is the best configuration. This 7.5” AR-15 upper chambered in .300 BLK is the key to building an ultra-compact shooter that packs a punch. Sporting a phosphate-coated, 4150V, mil-spec barrel, this upper guarantees accuracy in a small package.

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.
