Cross Armory's Safe Mag is a fixed magazine locking system for MIL spec AR-15 and M4 rifles. It prevents the removal of the magazine from your AR-15 or M4 rifle without disassembly of the action when properly installed. The Safe Mag is intended to be consistent with the fixed magazine laws which state that your weapon must have a "fixed magazine".
