Description

For shooters who want to maximize their range, accuracy, and style points, we’re introducing the 10.5” 300 Blackout AR Pistol Kit. This A2-profile barrel features a pistol-length gas system and is optimized for handling supersonic and subsonic 300 BLK cartridges with ease. We chose a 1:8 twist rate to provide reliable groupings with either loads, while the cold-forged 4150 CMV barrel goes to work guaranteeing MOA accuracy and incredible barrel life.

Out back, you’ll find a quality SBA Pistol Brace with a 5-position buffer tube. A carbine buffer works in tandem with an enhanced, polished trigger kit to ensure reliable cycling with any loads. Simply grab the optional forged or billet 80% lower, and you’ll have all the parts you need to turn a box of bolts and bits into a rugged, reliable AR pistol in a single day.
