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.

  • Ultra-fast magazine changes
  • Easy to install in 30 minutes or less
  • Featureless AR components no longer needed
  • No need to permanently modify your upper or lower
  • No need for bullet button
  • Available for any AR-15 or AR-10
  • 100% made in the U.S.A.
  • Finished in black or stainless steel
  • Patent pending
  • Custom modification required with Aero M5 lower

ORDERS OF 6 KITS OR FEWER WILL BE SHIPPED VIA USPS.

Very good alternative to F'd-up CA restrictions

Got my AR Mod kit - great fit and it works just like they said! Easy to install, but it does need some good lubing for the receiver lever to work freely.

Great alternative for a scrappy situation

Thank you guys for creating those solution for those of us living in this awful state when it comes to 2A rights. If you are looking for constructive suggestions on the already great product that you created, please make ambidextrous, and in a perfect world find a way fo the bolt to lock back once we run out on mag. Keep up the great work.

My CA AR that isn't

My CA compliamt mod kit is great! It was easy to install. It's easy and quick to use. My MSR has all the features allowed in other states but isn't an assault rifle by CA legal standards. Thanks Juggernaut!

Works but OVER$$$

Works as intended but in my opinion overpriced. It doesn’t run smooth when you’re trying to disengage both take down pins. If instead of a detent, it was a ball bearing of sorts to let the pin run smother, this product would break the internet!… It would be worth the money but for now…I’d say 30-40$ tops is the value of this mod.

It certainly works

It does its job. Adds a bit of play between upper and lower receivers but otherwise works. Sucks that such a product even needs to exist but thankful that Juggernaut is doing what it can to help Californians.

Easy to get used to

I have it on 5 or 6 of my rifles. By now it takes me maybe additional 1 second longer to release the mag and close it back up vs standard (normal) AR. Only complain is that I had to always check the knob as it gets lose and actually fell off a couple of times. I purchased some tiny rubber gaskets and it completely solved the problem. It would be a good idea if Juggernaut had a permanent rubber gasket inside to prevent the knob from getting lose. Otherwise a perfect solution to CA’s lame laws.

Issues with takedown pin design

Functionality, the JT kit works fine. However, 2 issues I've run into: (1) the button trends to loosen and unscrew after a day at the range. It hasn't unscrewed completely and fallen off (yet) but that would be an issue if it did. And (2) when you pull the takedown pin out to separate the upper & lower for cleaning you have to be REALLY careful to not let the detent pin slip off of the takedown pin. Otherwise, you're spending time precariously trying to push the detent pin back into place (while trying not to bend it). If the takedown pin could somehow be re-designed so that it keeps the detent pin pressed while pulling it out that would be awesome!

Good stuff!

I have other AR's with the armaglock and they work but they failed me at the same time (the catch loosen up over time no matter how tight or how much loctie you use) so when it came time to fix mag my next ar, i decided to look around and came across the jt tactical kit. Bought it and installed it and love it! I like how descreet the acutal locking portion is, way less intrusive than others out there. love the kingpin design, that offers you the ability to disasemmble the button and pull the pin out. After installing the first one, i ended up buying 3 more +1 for an ar10 and swapped out my other rifles. It still sucks to have fixed mag, but might as well make it a little convient. Will definitely buy another or reccomend this to others!

On the front end it was cool.

It was cool for a while but switched to a featuless build. The rear pin got bumped and bent slightly making it almost impossible to remove. Also if the bolt drops while and empty mag is inserted or if there is a malfunction it makes the firearm dangerously difficult to clear or open. And also very fiddly and annoying in general. Cool product lame compliance laws.

PHENOMENAL

I want to start by saying I was trying to install it upside down for at least 20 minutes. Once I figured out that I was a dolt, it dropped right in. Adjustments were easy, and I will admit, I didn't use any loc-tite as the video recommended, but haven't had any issues with that screw moving. I love having a featured rifle and the jugg kit makes it so terribly easy to just break the action - instead of one button to drop the mag, it's 2. My son is annoyed by it, but I think fully worthwhile.
