Juggernaut Hellfighter Kit’s main pieces includes:

Easy installation

In a span of not more than 10 minutes, I got to install this kit in my firearm. I’m very pleased with the result and how no sweat, it is for me to assemble and also when I’m about to use it.

Though with this Hellfighter, mag lock needs another step in the reloading process in approximately a second or less than the normal reloading time.

The way it works, isn’t that flashy or loud in the eyes unlike others that are unpleasant to look at when it comes to its visual looks and functions.

Trouble-free to maintain 

Whenever I remove the upper, I no longer need to undergo a troublesome removal process for it is designed to make it easier.

Once the threaded cap is unscrewed, the knob will rotate, resulting for the pin to be pulled just like the usual takedown pin. Double check if the other side of the cap is not attached. 



It has a genius design for a fast and easier loading work. Changing the old takedown pin and bolt catch is a nice move for it will result for a quick and controlled separation to the receivers. With the law, you can now legally remove and reload your magazines without restrictions. If aiming for a fast reloading of magazine, constant practice is needed.


Opening the kit, getting takedown pin with the spring, I untwist it both for them to separate. The mag lock comes with the adjustable details and also comes with two springs wherein I chopped the first spring in while leaving the extra for a while on the side. First step, I removed the rear takedown pin, take off the castle nut and loosen the buffer tube slightly. Taking out the buffer and spring then setting it aside.

After, I now loosen the castle nut and the in plate away from each other a little bit. Be careful not to lose the detent and spring while doing it. I twist the buffer tube to have access to remove my old takedown pin then inserted the new one immediately. Next, I inserted the spring making sure that it is aligned to clicked in its final spot. After I successfully inserted the new pin and spring, I putted back the castle nut and buffer tube together and made sure its all tighten– nice and snug. Lastly, putting the buffer and spring back to its original place. 

On uninstalling the old fly it bullets button, I disassembled the ball button using a bull pen tool and turn it counterclockwise. Pull it out while leaving the magazine catch installed. Take the factory magazine spring and button then insert it by pushing it both, applying some pressure and then start rotating it. Make sure that you can release the magazine freely. 

Installing the magazine lock, focus on removing the old factory bolt catch and installing the new magazine lock. First, remove the roll pin using a roll pin punch while keeping the spring and detent inserted. Before putting the new magazine lock, apply first a little glue (lock tight) to the set screw by screwing the detent all the way out but not till it comes out. After, bact it out even more then install it. 

Lastly, install the upper to complete the installation.

Key features

  • Fast magazine changes
  • Getting a Featureless AR components are unnecessary
  • Compatible with AR-15 and AR-10 platforms
  • Black finished
  • No longer needed for a bullet button


  • Instead of a lever, it is a button press system, making it easier when ejecting the mag. 
  • Doesn’t come with a pull out, pin so no need to pull out the rear takedown pin whenever I needed to open the upper and lower receivers. Also with a pull out pin, it slows down when reloading.


  • The screw in the kit that needed for the cap and spring is too short and there’s no other way to keep it in place so it keeps on loosing. 
  • Needs constant tightening of the screw whenever I changed mag.
  • Difficulty to select fire from safe position for the push button cramps the safety selector.
  • Using a lock tight is a must for there’s a chance that the springs might fall off without you noticing it.
