AR-15 LOWER RECEIVERS

Rugged, High-Quality Machined Forging For Building A Custom Rifle

Semi-auto, small pin lower receivers are premium-quality forgings machined to precise dimensions and ready to serve as the foundation of a fully customized tactical, competition, or hunting rifle. Exceptionally strong, rigid 7075 T6 aluminum forging has extra metal in the right places for added strength without unnecessary bulk. Features a beefy, M16A2-pattern reinforced area around the front pivot pin, a strengthening ridge over the receiver extension threads, and a ridge around the mag release button to guard against accidental magazine drop by preventing unintentional button activation. Bead blasted after machining to ensure a uniform, non-reflective surface before application of lusterless black military hardcoat A8625, Type III, Class 2 anodized finish that adds surface strength and resists abrasion. A final, nickel acetate seal coat provides extra protection against corrosion. Available as a complete, fully assembled lower, with fire control system, pistol grip, receiver extension, buffer, spring, and buttstock installed and ready for the upper receiver of your choice. Choose adjustable, six-position M4-style buttstock of high-impact, molded polymer, or fixed, A2 buttstock with “trapdoor” storage compartment just like original USGI rifles. Both stocks include sling loop at the toe. Stripped Lower is the perfect companion for Bushmaster Lower Receiver Parts Kit, available separately, and the receiver extension/buttstock system of your choice.
