Cross Armory SAFE MAG Fixed Magazine Locking System for MIL-Spec AR-15/M4 Rifles - CRSM

Overview

The Cross Armory Safe Mag is a specialized magazine locking system modification designed for AR-15 and M4 Mil-Spec rifles in regulated states requiring fixed magazines. It prevents the removal of the magazine without first disassembling the firearm action. When properly installed, the Safe Mag allows the magazine to release instantly when the upper and lower receivers are separated, disabling the action without requiring a traditional button press. It also permits the insertion of a fresh magazine while the receivers are closed, without placing undue stress or strain on the weapon's hardware.
