The Combat Armory billet AR-15 stripped lower receiver in Black (brand part no. STP.CA15.Lower.BLK) is machined from mil-spec 7075-T6 aluminum billet, giving builders a durable, precisely cut foundation for a rifle build. Combat Armory machines a Magpul-style trigger guard directly into the receiver, so there’s one less small part to install, and flares the mag well to speed up reloads. The company builds these receivers to a standard used by military, police, and firearms enthusiasts alike. Because it ships stripped, this lower is ready for the builder’s own parts kit, buffer, and stock. Among the lowers in the AR15 lowers category, the Combat Armory billet lower is built for shooters who want machined-in features without a billet-set price tag.
