The American Tactical Inc Milsport 5.56 NATO rifle is a semi-auto platform built around a 16 inch barrel and a 13 inch M-LOK hand guard for a clean, functional setup that supports modern accessory placement. A 1:8 twist rate helps stabilize a wide range of common .223 Remington and 5.56 NATO loads, while the threaded 1/2x28 muzzle provides compatibility with popular muzzle devices. Flip-up adjustable sights provide a ready-to-run sighting system that keeps the rifle usable right out of the box.
