The Phase 5 PMR is a CNC machined 6061-T6 billet aluminum magazine release button. Easy to install, the PMR is a drop in component that replaces the Mil-Spec magazine release button.
Including a textured angle serration design on the button face, the PMR adds style and keeps the function of a Mil-Spec button.
