AR-15 Lower Receivers
The Foundation of Your Build: AR-15 Lower Receivers
Start your next AR-15 Lower Receiver custom project on a rock-solid foundation with our selection. As the serialized heart of your rifle, the lower receiver dictates the quality, ergonomics, and compatibility of your entire build. We stock a comprehensive inventory of stripped and complete AR15 lowers designed to meet the needs of every builder, from the budget-conscious hobbyist to the precision marksman. Choose from classic 7075-T6 forged aluminum lowers for battle-proven mil-spec reliability, or upgrade to a CNC-machined billet lower for a modern, custom aesthetic with integrated features like flared magwells and threaded bolt catch pins.
Every AR-15 lower in our collection is engineered to exacting tolerances, ensuring seamless integration with standard parts kits and upper receivers across all calibers, including 5.56 NATO, .300 Blackout, and 6.5 Grendel. For those seeking a faster path to the range, our complete lower receivers come pre-assembled with trigger groups, buffer assemblies, and furniture from the industry’s top brands. If you prefer a full custom experience, our stripped lowers provide the perfect canvas for your specialized internal components. All serialized receivers require shipment to a Federal Firearms License (FFL) holder; we make the process simple with fast processing and coordinated delivery to your local dealer of choice.
