The Omni Hybrid 556 from ATI features the Omni Hybrid polymer lower receiver made of a fiberglass-composite polymer over a zinc metal insert which is lighter than most aluminum lowers, yet has the strength or more of a steel body lower. Designed to give extra strength in the high pressure sections, the Omni Hybrid surpasses military pressure and weight-bearing testing. It has an inter-lock hammer and trigger pin retainment system that prevents hammer and trigger pin movement during firing. THe hybrid is compatible with most AR-15 parts kits, grips, and stocks. The platform is flattop optics ready with an 16" Melonite coated barrel.
