Cross Armory’s SAFE MAG .308 is a modification, designed in California, for weapons in regulated states that require fixed magazines. The Cross Armory SAFE MAG .308 works by releasing your magazine instantly when you separate the upper and lower receivers of your .308 or AR-10, without having to press a button.

Cross Armory’s SAFE MAG .308 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 .308 or AR-10 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 .308 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 .308.

Cross Armory’s SAFE MAG .308 is a reliable, durable and easy-to-install magazine release. When paired with the Cross Armory’s QUICK PINS .308, magazine changes can be performed efficiently and with a minimum of inconvenience to the user.

Depending on your build, you will need to choose between the AERO & DPMS variations. Please see instructions below on how to measure when choosing between AERO and DPMS if you do not see your model listed here:

HOW TO CHOOSE BETWEEN AERO & DPMS
