These kits allow you to fix a 10-round mag in your AR-15 receiver using a set screw.
The kit includes the modified button, a 2-56 thread set screw, and a .035" allen wrench.
To install, simply replace your existing magazine release button with the one in the kit and use the allen wrench to tighten the set screw. When installed, the set screw will require a tool to remove, making it a fixed magazine under the current interpretation of California law.
To switch your AR-15 back to detachable-magazine configuration, just remove the set screw and the release button will work as normal.
