Receivers

Lower receivers form the serialized foundation of your AR-15 or AR-10 build, housing the trigger assembly, magazine well, and controls that define your rifle's performance. Whether you're assembling a precision range rifle or a reliable home defense platform, quality receivers from trusted manufacturers like BCM ensure proper tolerances, durable construction, and compatibility with standard parts kits. A properly spec'd lower receiver provides the solid foundation every custom build requires, giving you control over every component in your defensive firearm.
