American Tactical Alpha Maxx Features The American Tactical Alpha Maxx is built on the ALPHA-15 platform chambered in 5.56 NATO and .223 Rem with a 7.5 barrel threaded 5/8x24 that supports compatible muzzle devices and suppressors without additional machining and a 1:8 twist rate that stabilizes the full range of 5.56 and .223 projectile weights for consistent performance at the range. The polymer receiver keeps the overall weight at 6.95 lbs across a compact 22 overall length and the two-position thumb safety provides a straightforward positive control interface familiar to any AR-platform shooter. For shooters who want a compact suppressor-ready 5.56 NATO AR pistol with a high-capacity magazine included the Alpha Maxx delivers a complete package out of the box. The 7 M-LOK handguard with quick-detach rail gives shooters a versatile lightweight accessory mounting platform for lights lasers and grips suited to both range and personal defense configurations while the flip-up adjustable sights provide a reliable backup iron sight solution that co-witnesses with compatible optics. The A2 pistol grip and ATI Blade #2 pistol brace provide a stable ergonomic shooting interface that keeps the compact platform controllable and accurate during sustained range sessions. The included 60-round magazine gives the American Tactical Alpha Maxx a meaningful firepower advantage over standard 30-round AR pistol configurations making it one of the most capable high-capacity 5.56 pistols available for sale at GrabAGun.
