American Tactical LLC is using a fiberglass-composite polymer over a zinc metal insert to give extra strength in the high-pressure sections of the company’s new Omni Hybrid AR-15 lower receiver. At an MSRP of only $49.95, the Omni Hybrid stripped lower is one of the most cost-effective multi-caliber lowers on the market today.
“The Omni Hybrid lower has gone through all the pressure and weight-bearing testing of a traditional aluminum lower with flawless results,” says Joe Calabro, director of marketing for American Tactical. “We feel like this new manufacturing technique will help set the standard for AR lower manufacturing.” As well as cost savings, this unique manufacturing process produces weight savings—the total weight of the Omni-Hybrid stripped lower is 8 ounces, about a half-ounce lighter than a traditional aluminum AR lower.
