The ATI Alpha Maxx .300 Blackout pistol 7.5-inch FDE model is a compact semi-auto AR-pattern pistol that puts the .300 AAC Blackout cartridge in a very short package (American Tactical (ATI) part no. ATIGAX3007MLCFDE). Its 7.5-inch barrel has a 1-in-8 twist and a 5/8×24 threaded muzzle, ready for a muzzle device or a suppressor. A 7-inch polymer M-LOK handguard leaves room for a light or a vertical grip, and flip-up adjustable sights give it a sighting system out of the box. It ships with one 30-round magazine and wears an FDE finish over a black barrel. As a truck gun, a home-defense pistol or a suppressor host, the short .300 Blackout setup makes a lot of sense.
