The ATI MilSport 5.56x45mm is a modern sporting rifle built on a proven platform, designed for shooters who want genuine mil-spec features without unnecessary frills. This rifle chambers the ubiquitous 5.56x45mm NATO round, making it ideal for target shooting, sport competition, and home defense. The 16-inch barrel strikes a practical balance between velocity and maneuverability, while the threaded muzzle gives you the option to add a suppressor or muzzle device down the road. Whether you're building your first AR or adding to an existing collection, the MilSport delivers the backbone of a reliable, expandable platform.
The receiver features full Picatinny rail mounting on top, giving you plenty of real estate for optics, iron sights, or backup systems. The 13-inch M-LOK handguard provides modern attachment points for lights, grips, slings, and other accessories without the need for traditional picatinny slots—you get a lighter, cleaner profile. The 6-position Rogers Super-Stock lets you dial in your cheek weld and length of pull, and the black polymer grip is comfortable and durable through years of range use. The rifle ships with a 30-round magazine plus one additional round in the chamber (30+1 capacity), giving you factory-ready capacity for most shooting disciplines.
All the controls and furniture are finished in matte black, so there's no glare to give away your position on the range, and the non-reflective look pairs well with modern tactical setups or hunting rigs. This is a no-nonsense rifle: it's threadbare of gimmicks, heavy on compatibility with the aftermarket ecosystem, and ready to run out of the box.
