Description

Achieving perfect performance with .300 BLK is easy, if you buy the right upper. This 10.5” barreled assembly boasts a mil-spec (4150 CMV) barrel coated with a nitride finish, promising longer barrel life and MOA accuracy, especially compared to a chrome-lined barrel.

Inside, a pistol gas system and M16 BCG ensures you can reliably cycle light and heavy loads with no modification. 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.
