Phase 5 Weapon Systems
Overview
The Phase 5 Tactical AR-15/308 Oversized Magazine Release is an extended magazine release designed to improve the speed and efficiency of magazine changes. Made from aluminum and finished with a hardcoat anodized treatment, this part provides a durable and reliable interface for quick magazine drops. Builders frequently use this component in mid-length gas system configurations chambered in 5.56 NATO, where fast reloads can be particularly beneficial.

Availability is good: it was in stock at one retailer or another nearly every day in August 2026, and today 3 of the 5 retailers we track have it in stock. Prices barely moved in August 2026, holding around $18.99, so there haven't been real sales lately.

thumb hits it without breaking grip now. install was the standard mag catch swap, took maybe 4 min total. the oversized paddle has knurling so wet hands still grab it
