ATI Omni Hybrid Maxx 5.56 Poly Rcvrs 16 M4

American Tactical's Omni Hybrid Maxx features a fully-patented metal reinforced polymer upper receiver along with a fully-patented metal reinforced polymer lower receiver. The Omni Hybrid lower features a patented hammer and trigger pin retainment system, preventing movement from the hammer and trigger pin during firing. The Omni Hybrid also featured their 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. In addition a magazine is now included with all Omni Hybrid Maxx rifles.
