Phase 5 Weapon Systems PMR Magazine Release Button 6061-T6 Aluminum AR-15 - Black

The Phase 5 Weapon Systems PMR magazine release button is a precision drop-in upgrade for the AR-15 platform. CNC machined from a single piece of 6061-T6 billet aluminum, the PMR replaces the factory Mil-Spec magazine catch button with a contoured profile designed for fast, positive magazine drops during rapid reloads.

Engineered to fit 5.56/.223 and 7.62/.308 AR-pattern lower receivers, the PMR installs with no modifications required - it drops directly into the existing magazine catch as a true Mil-Spec replacement component. The black anodized finish is matched to standard factory parts for a clean, low-visibility appearance, and the lightweight aluminum construction adds virtually no weight to the lower receiver.

Whether you are building a custom AR from the lower up or simply upgrading the controls on an existing rifle, the PMR delivers a durable, ergonomically refined magazine release backed by Phase 5 Weapon Systems' reputation for quality precision-machined components.
