Description

300 Blackout: If you wanna build a close-range hand cannon that'll put a hole in just about anything, you've found the right kit. This AR-15 Build Kit sports a heavy-barreled 7.5" upper forged from 4150V gun steel - the same stuff the U.S. Army loves. Inside, a full-auto M16 BCG goes to work with a pistol gas system, reliably cycling any light or heavy loads. Just swap the magazine and keep burning brass.

This kit also comes with a forged M4 upper with plenty of rail space for your favorite optics and irons. You also get a lower parts kit with an upgraded Magpul MOE grip and polished trigger, a complete buffer tube assembly with a pistol brace by SB Tactical, and your choice of one of our forged or billet 80% lower receivers! Pair with a jig and get your build kit finished in a single afternoon. Then, just hit the range!
