ATI Mil-Sport Semi Automatic Rifle 5.56x45mm NATO 16" Black Threaded Barrel Black Frame Black Pistol Grip

The American Tactical Inc. Mil-Sport Rifle features a fully-patented metal reinforced polymer upper receiver along with a fully-patented metal reinforced polymer lower receiver. The Mil-Sport lower features a patented hammer and trigger pin retainment system, preventing movement from the hammer and trigger pin during firing. The Mil-Sport also features ATI's patented over-molded metal insert, which reinforces the buffer tube housing and rear takedown pin. This allows for metal-on-metal contact with both the buffer tube as well as the rear takedown pin thus increasing strength and durability from recoil and consistent firing.
