Strike Industries J Comp V2 for AK-47  

From William C.

The market for AK-47 accessories has been weak for years, largely it has been centered around different quad rail systems or making your AK-47 accept M4 style stocks. Thankfully new blood has been introduced into the AK-47 accessory market in the form of the Strike Industries J Comp V2. The folks at Strike Industries have taken a modern look at a classic muzzle device and brought it into the 21st century, for all the AK-47 owners who wanted an affordable and useful muzzle device that is a little out of the ordinary

Strike Industries has been around since 2011 and is the result of CEO Garrett Keelers hard work and innovation to constantly work at expanding the company’s offerings while not sacrificing quality and pricing. The company offers a huge line of accessories to fit a wide array of firearms from the traditional AK47 & AR-15 shooters all the way to the ultra-rare and very restricted Heckler & Koch MP7 Submachine gun chambered in 4.6mm x 30mm


The J Comp V2 muzzle device is based off the Type 89 Compensator that is commonly found on the Howa Type 89 Assault Rifle used by the defense forces and coast guard of the country of Japan. The Japanese, due to laws and restrictions, built their own military rifle and with that designed their own muzzle devices for that rifle. As joint Japanese-United States military efforts have continued for decades American servicemembers got an eyeful of the Japanese muzzle device and the legend of the Type 89 muzzle device grew. It was, however, practically unobtainable until… well that was until the folks at Strike Industries changed all that.

Sometimes it’s hard to make sense of the changing world of muzzle devices and what is the new magic pill in the world of reducing felt recoil and muzzle rise. That’s why we want to look at the specifications of the Strike Industries J Comp V2 muzzle device and what those are meant to accomplish.

When I first received the Strike Industries J Comp V2 I noticed its longer than most other muzzle devices I have experience with. This isn’t a negative thing just a general observation about its dimensions. The J Comp V2 is a good-looking muzzle device and the designers seemed to work a blend of form and function to give a part as small as a muzzle device a bit of flare to it. Further inspection of the J Comp V2 shows that the device features two large chambers and two smaller chambers located in the 3 and 9 o’ clock positions. They definitely will expel any concussive force away from the shooter and keep the muzzle from rising during rapid firing.

The top of the unit however only features two small holes to direct gas upwards, this is a bit puzzling to me, especially for a unit designed to help stop muzzle rise.

Installation and Use   

Installing the J Comp V2 muzzle device is very straightforward if you have any experience with left handed 14-1 threads. This left-handed thread pattern is the opposite of practically every other threaded muzzle in the known world. It’s part of the Soviet origin weapons charm. A point to note here is that the Strike Industries J Comp V2 does not come with a crush washer. In fact, I don’t think I can remember an AK-47 muzzle device ever coming with one.


The range session for the J Comp V2 is coming in the very near future at my local range. I intend to test it side by side with two other brands of popular muzzle devices on my AK-47 clone. If I’m lucky I might be able to borrow a friends select fire AKM and really test the compensator out a bit. It’s one thing to test a muzzle device on semi auto but it’s a completely different animal to test that same unit out under short burst fully automatic fire. During full auto bursts, any muzzle rise that is normally felt on a rifle will of course increase dramatically.


We have laid out a fine selection of the dirtiest Wolf and Tula ammunition that I could find locally for our upcoming range session. I personally never feed any of my AK series rifles anything but the cheapest rounds I can find. In my mind if an AK can operate on a steady diet of Eastern European 7.62×39 then it can run on anything made with reloadable brass. I am bringing along a few friends so we can form a collective opinion about the Strike Industries J Comp V2, those friends also happen to own AK’s so I may donate the compensator to one of them by the end of the day. One thing is for sure, at the end of the day 500 rounds of 7.62 x39 ammunition will be shot through the J Comp V2 and we will see if it lives up to the hype.
