Strike Industries J-COMP 2.0 for 7.62 Caliber AK Rifles

Strike Industries now makes an improved version of their J-COMP muzzle device for AK rifles. The new J-COMP 2.0 comes with a 14×1 left-hand metric thread pitch, which is used in most AK-47 rifles and its derivatives chambered in 7.62x39mm caliber.

The J-COMP 2.0 is actually a muzzle brake and compensator hybrid. It features two muzzle brake chambers and has an improved geometry which results in better muzzle rise compensation compared to the previous model. It is also compatible with Oppressor and FerFrans blast mitigation devices.

The compensator comes with a crush washer, but it also has a notch at its base for alignment and retention via a conventional plunger detent found in most of the AK-style rifles. J-COMP 2.0 weighs 3.6 oz, it has an overall length of 2.55″ and outside diameter is .87″. It is listed on Strike Industries’ website at MSRP of $39.95.

The J-COMP 2.0 design is based on the Japanese Howa Type 89 rifle’s muzzle device. Below is the image of that rifle’s front portion:

The idea of bringing military muzzle devices into the civilian market is pretty interesting. Many of such designs are not just the result of somebody’s imagination or made to look good over being practical. Considering that military adopted devices have already passed many tests and trials, it is a wise move to bring them to the civilian market.

    Exciting! My m90 needs this

    It’s not exactly a Gogun Supercomp (also available in 14×1 AK) but Strike has some great products at reasonable prices.

    I got one of these for my AR because I liked the look.

    I actually prefer version 1 but I think they were discontinued. Version 2 is still pretty cool.

    I’ve always preferred actual military style brakes and hinders over the $80+ civilian stuff.

    How is the J-Comp on shockwave? I’ve heard good things about it for the effectiveness, but shockwave is worse for the aim than recoil.

    • Xtorin O’hern

      i think you mean concussion, and the J-comp is pretty light on concussion but it is also not as effective as other more concussive brakes.

  • Scott Connors

    Is it marketed at all as a flash suppressor?

    • Flounder

      I bet marketing says it can, but officially and practically it is just a break. You should be gtg in restricted places.

      And It’s super cheap, the normal version is under 50 always, sometimes as low as 35

    Reasonably priced firearm accessory?

    Thanks, Trump.
