The Omni-Hybrid from American Tactical Imports is a fiberglass-composite polymer over a zinc metal insert. Designed to give extra strength in high-pressure sections, the Omni-Hybrid surpasses military pressure and weight-bearing testing. This unique manufacturing process produces a lighter weight platform at 8 ounces. The Omni-Hybrid stripped lower has an MSRP of $49.95, making it one of the most cost-effective lowers on the market today.
