The ATI Alpha Maxx delivers reliable performance in the versatile 300 Blackout caliber, combining a lightweight polymer construction with proven AR-platform functionality. This semi-automatic rifle features a 16-inch threaded barrel optimized for both supersonic and subsonic ammunition performance.

What Makes This Different

The Alpha Maxx stands apart with its all-polymer receiver construction that reduces overall weight by approximately 1.2 pounds compared to traditional aluminum receivers while maintaining structural integrity. The integrated Picatinny rail system provides unlimited optics mounting options, while the 9-inch polymer handguard offers ample space for accessories without adding unnecessary bulk. The threaded barrel accepts standard 5/8x24 muzzle devices including compensators and suppressors.

Key Features

  • 300 Blackout chambering handles both supersonic and subsonic loads effectively
  • Lightweight polymer receiver reduces carry weight without sacrificing durability
  • 16-inch threaded barrel (5/8x24 TPI) ready for muzzle devices
  • 30-round magazine capacity provides extended shooting sessions
  • Full-length Picatinny top rail accommodates any standard optic mount
  • 9-inch polymer handguard with M-LOK compatibility for accessories
  • ATI MM4 synthetic stock provides consistent cheek weld and length of pull
The 300 Blackout cartridge excels in multiple applications from hunting medium game at moderate ranges to home defense scenarios where over-penetration concerns exist. The 16-inch barrel length optimizes velocity for both 110-grain supersonic and 220-grain subsonic loads. Weather-resistant polymer components maintain functionality in adverse conditions while the standard AR-15 trigger group ensures familiar operation for experienced shooters.
