The ATI Alpha Maxx, chambered in .300 AAC Blackout (American Tactical / ATI part no. ATIGAX3007MLCFDE), is an AR-pattern pistol, not a shouldered rifle, built around a 7.5-inch barrel and a durable polymer lower for a lightweight, maneuverable package. It arrives optics-ready with flip-up iron sights and a 30-round magazine, and the 7-inch M-LOK handguard with integrated Picatinny rail space makes it easy to add a light, sling mount, or foregrip. The FDE finish and compact footprint suit close-quarters training, truck-gun duty, and home defense equally well. Because it ships without a shoulder stock, it is sold and transferred as a pistol rather than an NFA-regulated short-barreled rifle.

Key Specifications

• Configured as an AR-pattern pistol, not a shouldered rifle, so it transfers as a standard Title I firearm with no tax stamp required.
• Chambered in .300 AAC Blackout, giving strong terminal performance from a short barrel in both supersonic and subsonic loads.
• The 7.5-inch barrel keeps overall length short for maneuverability in tight spaces.
• A rifling twist rate of 1-in-8 inches is matched to stabilize heavier .300 Blackout subsonic bullet weights.
• Ships with a 30-round magazine for a full-capacity first loadout.
• The muzzle is threaded 5/8-24, ready for a compensator, flash hider, or suppressor.
• The barrel wears a black finish for durability and a low-visibility look.
• Includes adjustable flip-up sights, giving a folding backup sighting system alongside any optic.
• A 7-inch polymer M-LOK handguard with full-length Picatinny rail space allows easy mounting of lights, optics, and accessories.
