The button is aluminum and will come with an allen wrench. It can be used on all AR-15 type rifles and AR-10 rifles using a stock AR-15 button.

The button can also be used as a real magazine release button when using it as such is permitted by law. Simply turn the allen screw counter clockwise three times to gain such functionality. Turning it three times clockwise re-locks the magazine. To complete turns either way, you are required to use the included allen wrench, which meets the requirements of a tool as set forth by the CA DOJ.

This kit cannot be manipulated without a tool.

Included are instructions for several levels of locking. Level one is more than adequate for complying with the law as stated by the State of California.

Level 2 will be to remove the spring and use one setscrew.

Level 3 will be to remove the spring, and add another setscrew on top of screw #1

Level 4 will explain how to epoxy or superglue the second screw in place.

In order to load your magazine, you need to disengage the rear take-down pin, pivot the upper receiver open. Once open, you can now top load your magazine while still locked to lower receiver.
