ATI Alpha Maxx | 5.56 NATO | 16″ Barrel | 60+1

The American Tactical / ATI Alpha Maxx is a semi-automatic AR-pattern rifle chambered in .223 Rem/5.56 NATO with a 16″ barrel and a 15″ M-LOK handguard. It ships with a 60-round window magazine and a polymer receiver, and features a threaded muzzle with a 1/2×28 thread pattern for common muzzle devices.
