California Compliant AR Mod Kit
The Hellfighter Mod Kit is compatible with any AR-10.
By changing out your rear take down pin and replacing it with our modified take down pin in combination with a new bolt catch now used as a magazine lock, you will have a completely California Compliant AR. You no longer have to use a Featureless AR solution. Our system will allow you to keep all of your current features, including a pistol grip, a forward grip, and adjustable butt stock. You can even reinstall a mil-spec magazine release. No need for a bullet button.
