Description

The FMK Firearms AR-1 eXtreme is a stripped lower receiver for building an AR-15 style rifle. It is made from a proprietary composite polymer rather than the aluminum used in most traditional lowers, and it is designed to serve as the foundation of a custom semi-automatic firearm.

The receiver weighs 7.2 ounces and has a matte Burnt Bronze finish. It is listed for 223 Remington and 5.56x45mm NATO calibers and fits the AR-15 mil-spec platform. The action is semi-automatic.

This is a stripped lower, so it does not include a fire control group, buffer tube, stock or other components, which must be sourced separately to complete a build.

  • Calibers: 223 Remington, 5.56x45mm NATO
