Questions & Answers
Will this setup hold the bolt open when you run out of ammo? Expert Answer

This does not interact with your bolt catch, rather this is a rear takedown pin assembly replacement. The bolt catch assembly is sold separately.

The Juggernaut Tactical California Compliant AR-15 Magazine Locking Kit should work with a TriggerTech Drop In Trigger.

Juggernaut by Eric, July 27, 2022
Perfect for CA rifle owners to keep your AR15 with all the features. Easy to install. A must for any ar15 owner in California. Better then having a flip for grip. What else do you need to say. Things just keep getting expensive, get it now while it’s...

safe act nys? by mike, December 9, 2020
Is this legal for NYS? In New York if an AR has a fixed mag your allowed to have all the normal stuff. Does this make an AR safe act compliant? New York has the dumbest gun laws. No pistol grips if your semi automatic rifle has a detachable magazine.

Product Info for Juggernaut Tactical California Compliant AR-15 Magazine Locking Kit

The Hellfighter Mod Kit is compatible with any AR-15.image

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.

We are proud to introduce the Hellfighter Mod Kit, the perfect, ultra-fast California Compliant magazine lock solution for your 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 take down 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 take down pin and will quickly get you back in the fight.
