The Defender AR15 Mag Carrier is no ordinary AR mag holster. We make our AR15 magazine carriers, AR10 mag carriers and AR mag holster molds in-house allowing us to have a better design that holds your AR15 and AR10 magazines firmly in place. You can choose from a variety of mounts and colors for your new AR15 and AR10 magazine holsters. We also offer our connect series that allows you to connect a second AR15 magazine holster or a double pistol mag carrier to our AR15 holster.
