Stripped Lower Receiver AR-15/M4

Stripped Lower Receiver AR-15/M4

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. Stripped Lower is the perfect companion for Bushmaster Lower Receiver Parts Kit, available separately, and the receiver extension/buttstock system of your choice.
