If you need an effective and high-class compensator for your rifle, you will like the J COMP concept by Strike Industries. Strike Industries is composed of avid owners of AR-15s and pistols. Because the AR-15 platform is extremely versatile, there are a wide variety of customization options available for purchase, but not all of these are worth buying. Strike Industries products are designed for active shooters by those who understand the everyday needs of an AR-15 owner.

The Strike Industries J COMP is based on the Type 89 Japanese assault rifle used by certain branches of the Japanese armed forces. The J COMP is one of three Japanese-type compensators designed by Strike Industries for customers.

The J COMP muzzle brake is specifically designed to reduce recoil. A double chamber system and six ported side vents redirect the explosive force of the gasses created by firing your rifle. The front ports of the J COMP minimize flash to decrease your signature when out in low-light situations, thereby helping to protect your night vision. Efficient night vision in low light makes it easier for you to perform accurate follow-up shots.

The smooth parkerized steel finish gives the Strike Industries J COMP a clean appearance that won’t be found amiss on the muzzle of your AR-15. The J COMP is rated at 4.82 out of five points by law enforcement officers for ease of use, performance, comfort and quality. If you want to reduce the recoil of your firearm and give an extra “oomph” to its appearance, the J COMP muzzle brake is for you.

    This comp is very effective and at a rock bottom price. I have it on other rifles as well. You won’t be disappointed.

  • J Comp Type 89 Compensator

    Posted by Jim on 26th May 2019

    Great look and fit for my Ruger-556 MPR. The stock muzzle break was disturbingly loud, though with notably acceptable flash suppression and nice recoil dampening. The J-Comp excels at all three points. I do feel a bit more recoil, but the flash and sound suppression are worth the tradeoff.

    The crush washer is an absolute necessity for this rifle. If you don't have a torque wrench get your trusted gunsmith to put it on for you, because the ports must be in the right place on the muzzle to to their job; whilst securely fastened.

    Chances are you'll never have to replace this compensator, but if so, get a new crush washer EVERY time. Shoot straight!

  • Great function and good for the money

    its beautiful piece mitigating recoil and muzzle rise. Free hand rotation onto the barrel at around 10 o'clock position so it just needs slight turn to be dead on center. The J comp by itself is at a great price point. It's also compatible with SI's blast forward can although that set up a bit over priced in my opinion.

  • Awesome Muzzle Brake

    I put this on my Ruger AR-556 and it does exactly as it should. The Muzzle stays down and along with my 3lb velocity trigger, my gun is fast and accurate!!!!

    Strike Industries J comp is awesome! Comes with a crush washer. This compensator requires a wrench other than the armorer's wrench to install. I highly recommend it, because it reduces muzzle rise and recoil. Also gives my AR 15 diamond fluted .223 wylde barrel an aggressive look.
