The S&W M&P15 assembled lower receiver is an AR-15 lower built for 5.56 NATO and .223 Remington platforms. It comes in black with a manual thumb safety, and the package includes a standard trigger group and a collapsible stock setup. The receiver is designed for a standard AR-15 receiver extension and uses a standard AR-15 grip. The single-stage trigger characteristics are the standard AR-15 type, which suits a builder who wants a familiar configuration.

This assembled lower fits a traditional AR-15 build where the shooter wants standard parts and a familiar layout. It works for range practice and for a builder who wants a straightforward starting point for a rifle. If you plan to hunt with the finished rifle, check your state wildlife agency's rules for AR-15 rifles and calibers, because seasons and legal firearms are set at the state level.
