The base for the ultimate precision tactical AR-15 rifle, the Billet-AR lower receiver is 100% machined in the USA. It was engineered from the ground up to address structural design weaknesses in standard USGI lower receivers and enhance overall tolerances. The Billet-AR lower receiver has been enhanced with an oversize magazine well for quick reloads and an integral trigger guard for gloved use and added lower receiver strength.
