AR-15/M16 FREELOCK MINI CONVERSION KIT

Lets You Quickly Switch Between Fixed Magazine & Standard Detachable Mag

Easy-to-install kit converts a Mag Lock Bullet Button® to a dual-mode magazine catch that lets you switch easily between a fixed magazine configuration and a standard, detachable box magazine. Replace the Bullet Button center nut with the FreeLock, using the included tool to screw the FreeLock all the way into the Bullet Button housing and lock the magazine in the rifle. Use the tool to unscrew the FreeLock until the Bullet Button operates like the standard mag release to drop the magazine.
