Aero Precision, Ar15 Standard Complete Lower Receiver, Anodized

The Aero Precision AR15 Standard Complete Lower Receiver in anodized black provides a ready-to-assemble foundation for anyone building on the AR-15 platform, and as part of Aero's AR15 Standard series this Gen 2 lower delivers the fit and machining tolerances builders expect from a reputable OEM. It arrives fitted with a mil-spec lower parts kit for reliable fire control components, an M4 carbine stock and carbine receiver extension for standard length-of-pull adjustments, and an A2 grip for classic ergonomics that many range shooters and hunters prefer. The included AR15 carbine buffer and spring tune recoil impulse and cycling for common carbine gas systems, making this lower ideal for range practice, tactical training, duty-style builds, or a hunting rifle when paired with the appropriate upper. Anodized black finish resists wear and provides consistent surface protection while maintaining compatibility with aftermarket parts and AR-15 accessories, so builders can swap uppers, barrels, and handguards to suit caliber choices and mission profiles without concern for fitment.
