American Tactical Imports (ATI) has recently developed the Omni Hybrid, a new fiberglass-composite polymer lower receiver for an AR. But unlike most polymers lowers, this one is steel-reinforced with an insert. It includes an integrated enhanced triggerguard and a beveled magazine well, and weighs 0.5 ounces less than a traditional aluminum receiver. ATI also offers it as part of a complete rifle with an aluminum upper receiver and a Melonite-coated, 15-inch barrel. For more information, visit americantactical.us.
