ATI ATIGAX5567ML60 Alpha Maxx 5.56x45mm 60+1 7.50" Black Threaded Barrel, Polymer M-LOK Handguard, Black Polymer Stock

The ATI Alpha Maxx 5.56x45mm is a modern, modular rimfire-style plinker built on a pistol platform with serious customization potential. This 7.5" threaded barrel rifle delivers the compact handling of a short-barreled platform while chambering the practical, widely-available 5.56x45mm cartridge. Whether you're setting up a truck gun, a fun range shooter, or a compact defensive option, the Alpha Maxx's aluminum and polymer construction keeps weight down and flexibility high.

The M-LOK handguard gives you genuine accessory rail real estate for lights, lasers, grips, or whatever mission-specific gear you want to bolt on. The threaded barrel opens the door to suppressors or muzzle devices tailored to your build. The black polymer furniture and stock keep the whole package lightweight and durable—built to take hard use without flinching. A 60+1 round capacity means you're loading once and shooting long, which is exactly what makes this gun fun at the range or effective in a pinch.

ATI has engineered this as a shooter's platform, not a display piece. The M-LOK slots are modern and widely supported by aftermarket vendors, so you're never locked into one ecosystem. If you want a 5.56 pistol-caliber platform that rewards tinkering and doesn't pretend to be something it's not, the Alpha Maxx is straightforward and honest—a rifle that works and lets you make it your own.
