The AR lower receivers are precision CNC machined from a solid block of billet aluminum. The receivers accept all Mil-Spec AR15 components and feature original Mil-Specs. The receivers are fully compatible with all standard AR uppers, including the 6.8 and 50 Beowulf. “Introducing the stripped AR lower is something we are very excited about,” says Uli Wiegand, CEO of I.O., Inc. “Our lowers are manufactured with the most technologically advanced equipment on the market today. This insures the best quality and reliability possible. Our lightweight AR lower platform enables the user to switch between multiple calibers and gives them consistent reliability and solid performance.”
