The ergonomics and control of the AR platform have made leaps and bounds in the decades since the development of the original Stoner design. By incorporating some of the best into our design, the ASF-20™ gives both right- and left-handed shooters unparalleled control in a JP rifle. This receiver design combines the A-DAC™ (Ambidextrous Dual Action Catch) system from Radian Weapons with our own JP Ambi Mag. Release. The result is a sleek yet rugged receiver offering full ambidextrous controls for the left-handed shooter plus bolt lockback and release for right-handed shooters without releasing the pistol grip.
Whether for a versatile 3-Gun rig, hunting rifle or duty/defense system shared by multiple users, the ASF-20™ answers the call. The ASF-20™ is compatible with any Mil-spec pattern upper receiver to serve as the cornerstone of any rifle project. Whatever your need, we’ve made the ASF-20™ ambi lower accessible:
