Cross Armory’s SAFE MAG is a modification, designed in California, for weapons in regulated states that require fixed magazines. The Cross Armory SAFE MAG works by releasing your magazine instantly when you separate the upper and lower receivers of your AR-15 or M4, without having to press a button.

Cross Armory’s SAFE MAG is intended to be consistent with the fixed magazine laws which state that your weapon must have a “fixed magazine” which has been defined as “an ammunition feeding device contained in, or permanently attached to, a firearm in such a manner that the device can not be removed without disassembly of the firearm action.” The firearm action of an AR-15 and M4 is housed in the upper and lower receivers. Separating the upper and lower receiver to release your magazine disables the firearm action.

Cross Armory’s SAFE MAG also allows for insertion of a new magazine when the upper receiver and lower receiver are closed, without bending or stressing the hardware of the weapon or of SAFE MAG.

Cross Armory’s SAFE MAG is a reliable, durable and easy-to-install magazine release. When paired with the Cross Armory’s QUICK PINS, magazine changes can be performed efficiently and with a minimum of inconvenience to the user.

FAQ – Frequently asked question:

What is the difference between each Safe Mag?

All the Safe Mag’s function the same way, by automatically releasing the magazine when you separate the upper and lower.  The different models (MIL/DPMS/AERO/2) differ in size and shape in order to fit various models of AR-15 and AR-10.

Safe Mag MIL-Spec is for MIL – Spec rifles only (not all AR’s are MIL Spec) and automatically drops the mag when you separate the upper and lower receivers.
Safe Mag 2 is designed for all AR-15’s and works and functions exactly the same as Safe Mag MIL-Spec, but it’s shape is a bit different so that it will fit on all styles of AR-15 type rifles
SafeMag AERO – is for AR-10 rifles that are made in the AERO style and size
SafeMag DPMS – is for AR-10 rifles that are made in the DPMS size and shape.
