ATI Alpha Maxx AR Pistol 5.56 NATO 7.5" Barrel 30+1 Capacity

The ATI Alpha Maxx AR pistol delivers compact firepower in the popular 5.56x45mm NATO chambering with a 7.5-inch barrel configuration. This pistol-length platform provides maneuverability advantages over full-size rifles while maintaining effective terminal performance at close to moderate ranges.

What Makes This Different

The Alpha Maxx features a direct impingement gas system optimized for shorter barrel lengths, ensuring reliable cycling with standard 5.56 NATO and .223 Remington ammunition. The 7.5-inch barrel length strikes a balance between portability and ballistic performance, generating approximately 2,400 fps muzzle velocity with 55-grain ammunition. ATI's manufacturing process includes proper headspacing and chamber finishing to mil-spec tolerances.

Key Features

• 7.5-inch chrome-moly vanadium steel barrel with 1:7 twist rate
• Standard AR-15 magazine compatibility accepting STANAG pattern magazines
• Forged aluminum upper and lower receivers with Type III hard anodizing
• M4 feed ramp extension for improved feeding reliability
• Picatinny rail system for optics and accessories mounting
• Standard carbine buffer system with commercial-spec receiver extension
• A2 flash hider with standard 1/2x28 threading

Field performance shows consistent accuracy within 3-4 MOA at 100 yards with quality ammunition, suitable for close-quarters applications and tactical scenarios. The shorter barrel length produces increased muzzle blast and flash compared to rifle-length configurations, making the flash hider particularly important for low-light operations. Reliability testing demonstrates consistent function with brass-cased ammunition across temperature ranges from -20°F to 140°F.
