Our Desert Eagle Magazine Carriers are designed to work with all makes and models of Airsoft Desert Eagle Magazine*. All of our Pistol Magazine Carriers use an MRD (Magazine Retention Device) which provides adjustable retention to the front of the magazine, allowing the carrier to hold on to the magazine with the perfect amount of resistance. To adjust the retention on the Magazine Carriers you need to screw or unscrew the silver grub screw found on the side of the carrier with a 1/8” Allen key/hex key. Please note that the magazine can only be inserted into the Magazine carrier in one orientation.
