California Compliant AR Mod Kit

We are proud to introduce the Hellfighter Mod Kit, the perfect, ultra-fast California Compliant magazine lock solution for your AR-10 or AR-15. This comes after a year of engineering and countless attempts to make the best and simplest solution on the market. With this bolt-on solution (patent pending), you will be able to perform magazine changes faster than you ever thought possible.

One of the features that sets us apart is our modified quick-release takedown pin, which acts as a button to separate the upper from the lower just enough to disengage semi-automatic operation and automatically disable the magazine lock. Once your upper is separated and disengaged from semi-automatic operation, your magazine release is now operable. A simple tap closes the upper and re-engages the spring-loaded takedown pin and will quickly get you back in the fight. The Hellfighter Mod Kit is compatible with any Mil-spec AR-15 or DPMS Platform AR-10. AR-10 Kit will work with either back or bottom-fed detent.

How it works:

By changing out your rear takedown pin and replacing it with our modified takedown pin in combination with a new magazine lock that replaces your factory bolt catch, 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. To purchase a standard magazine release button, click here.
