Description

Looking for the perfect 300 Blackout setup for your AR-15 build? The good ole’ whisper round can be finnicky, especially when it comes to velocity and twist rate. So, we branched out into shorter-barreled kits to satisfy the .300 BLK’s fickle behavior. Sporting a 10.5″ barrel made from mil-spec 4150 CMV with a 1:8 twist rate, this is the kit you want for MOA accuracy with light and heavy loads.

Rounding out this badass kit is a forged M4 upper with loads of rail space for optics and irons. Inside, you’re getting the best of the best: An enhanced trigger kit, a full-auto, staked and chrome-lined M16 BCG, and a pistol-length gas system for ultimate reliability. Out back, an SB Tactical pistol brace, full buffer system, and optional billet or forged 80% lower complete the kit. Pick up an 80% jig and you’ll have everything you need to turn this box of parts into a range-ready shooter! The upper ships prebuilt and test-fired, and everything’s backed by a Lifetime Warranty.
