Lower Receiver

The lower receiver is the serialized, legally-regulated component that serves as the foundation of your AR-15 build. It houses the fire control group (trigger assembly), magazine well, and provides attachment points for the stock, grip, and upper receiver. As the only part requiring an FFL transfer, choosing a quality lower receiver is crucial for your build's reliability and longevity.
