Maxim Defense MD15 AR-15 Complete Lower Receiver

A feature-rich complete lower receiver takes the guesswork out of sourcing a pistol grip, trigger guard, and stabilizing brace individually for a build.

The Maxim Defense MD15 Complete Lower Receiver is a fully assembled lower receiver designed to offer a solid, feature-rich foundation for an AR-15 build.

A mil-spec lower parts kit and Maxim pistol grip come installed from the factory, along with an extended trigger guard for added room during use. The integrated Maxim OEM 3-position adjustable PDW pistol stabilizing brace offers enhanced stability and control, and a QD attachment point on the housing adds mounting versatility.

This lower does not include a buffer weight or spring and is not compatible with Maxim CQB or SCW buffer systems, so builders should plan to source a compatible buffer separately.

Machined from durable 7075 aluminum and finished with a hardcoat anodized coating, this lower receiver is built to withstand rigorous use over time.

This lower receiver suits a builder who wants a feature-rich, brace-equipped foundation for a compact AR-15 pistol build without sourcing a grip, trigger guard, or brace separately.

Maxim Defense is U.S. veteran designed and made in the USA, building components focused on stability and control for compact AR-platform builds.
