Find your perfect 300 Blackout AR-15 Pistol from Pro2a Tactical! Tested rigorously for quality assurance and backed by our limited lifetime warranty, our pistols are ready to shoot right out of the box. 300 BLK offers more stopping power than 5.56 at closer distances and is one of the best calibers to be used with a suppressor. We even offer a special 1/5 twist in our 7.5 inch and 10.5 inch barrel lengths specifically designed for subsonic ammunition.
