Configured correctly, the 300 Blackout pistol can take out a wild hog from 200 yards with a subsonic suppressed round in a single shot. Or, it can reliably sling supersonic loads to 300 yards and beyond -- all without any modification, all tucked into a compact, lightweight package. That's what we strive to offer with every 300 Blackout Pistol Kit we make and sell.
Building a reliable 300 BLK AR pistol means getting the perfect barrel and gas combo. So, we preassemble each upper to guarantee reliability and accuracy. That's whether you shoot supers or subs, with or without a suppressor. Each 300 Blackout pistol kit includes almost every part required to complete your build:
Each kit ships with a 1:7- or 1:8-twist barrel. Both twist rates reliably stabilize supersonic and subsonic loads. The 1:7 favors subs and 1:8 favors supers. All uppers use exclusively pistol-length gas systems with 3.0-ounce Carbine buffers to guarantee your bolt never short-strokes or fails to chamber or eject a subsonic round. Each kit is finished off with a reliable (and comfortable) Adjustable Pistol Brace.
To complete your 300 Blackout pistol, you will also need to purchase an 80% lower receiver for the AR-15 platform. Or, you can purchase a stripped AR lower from a licensed dealer.
Contrary to federal law, some states have banned these kits and 80% lowers. We cannot fulfill orders to certain states. Before ordering, please check our Shipping & Returns Policy to ensure you do not live in a restricted state.
Your 300 BLK pistol awaits.
