Phase 5 Weapon Systems Extended Bolt Release V1 – AR-15/M16

The Phase 5 Extended Bolt Release V1 replaces the standard AR-15 bolt catch with an enlarged paddle that provides faster, more positive bolt manipulation without adjusting your firing grip. Designed for shooters who want quicker reloads and more efficient malfunction clearances, this extended release allows thumb-side actuation during mag changes and easier left-hand operation for southpaw shooters.

Machined from steel with a black oxide finish for corrosion resistance. This is a drop-in replacement for milspec AR-15 and M16 bolt catches—no permanent modifications or gunsmithing required. Installs with standard AR-15 lower receiver tools and a roll pin punch.
