Auto Magazine Releasing – AR MAGLOCK Gen 3 AR-15 (.223 / 5.56) Fixed Magazine Lock:

The brand new Gen3 AR MagLock features a reverse spring for auto releasing the magazine once the upper is lifted. It also features a Delrin roller that will protect the upper receiver from wear and tear.”

The AR MAGLOCK Gen 3 locking kit is one of our upgraded high performance kits for customers wanting an automatic magazine release upon last round fired. Priced affordably, this kit is like no other on the market, giving the user the speed of quick magazine changes when paired with the Hyperswitch.

This is the same kit many of our large OEM’s such as Daniel Defense, Armalite, Black Rain Ordinance and others purchase to make their rifles compliant for shipping into California.

If you would like a higher performance kit that allows faster double feed clearing, please upgrade your Gen 4 kit with a KingPin.

    The Gen 3 seems like a great system when installed properly. However, no instructions included on how to install the delrin roller and the magazine reverse spring. An updated installation video for the Gen 3 and Patriot pin installation would be helpful.
