ATI Alpha Maxx AR Pistol – .300 Blackout, 8.5" Barrel, 7" M-LOK Rail, Rear Brace

The ATI Alpha Maxx AR Pistol in .300 AAC Blackout combines compact maneuverability with the powerful terminal performance of .300 BLK. Built around an 8.5-inch barrel and a 7-inch M-LOK free-float handguard, the Alpha Maxx offers a short, agile platform ideal for close-quarters defense, fast-handling range work, and short-range hunting tasks such as hogs, deer in dense cover, and predator control.

Its M-LOK rail provides ample mounting points for lights, grips, and other accessories while keeping the profile slim and lightweight. Configured as an AR-pistol with a rear stabilizing brace, the Alpha Maxx is optimized for quick target transitions and controllable follow-up shots. ATI engineered this model for shooters who want the utility of an AR platform in a compact form factor — perfect for maneuvering in tight spaces or operating from vehicles and blinds.
