The JK 155 VERSAX 9K is a lightweight, modular suppressor built to handle just about everything in the 9mm world—and then some. From handguns and pistol-caliber carbines to lever guns and even rifle-caliber carbines, this compact K-length suppressor brings versatility and performance in a sleek, configurable package.
Made from 7075 billet aluminum and designed around JK’s six-baffle Mission Configurable system, the VERSAX 9K lets you tune for length, weight, and suppression with no special tools. Despite its low weight, it’s rated for serious energy levels—everything from .22 LR and full-auto 9mm to 300 BLK, 8.6 Blackout, 338 ARC, 350 Legend, and even 300 Win Mag when firing .36 caliber or smaller projectiles.
Whether you’re running drills with your carry gun, stretching out a PCC, or setting up a lightweight hunting rig, the VERSAX 9K is a do-it-all solution that won’t weigh you down.
Please note, this suppressor comes with a mount only and not a muzzle device. Be sure to check out JK Armament’s War Eagle and Bald Eagle muzzle devices!

This is my second JK can and love the versatility. I have used it on MP5 all the way up to 28 Nosler. For the price and modularity you can’t beat them. It is not my ‘quietest’, but the ability to shorten the length and weight is great.

I enjoy this product it’s everything as described by JK, what made me decide on it the ability to change it size

So have this suppressor but haven’t been able to shoot it. The description says threads are hub compatible but the diameter of the suppressor past the hub is smaller than the threads making a lot of hub adapters not actually compatible. I have this for my PCC and was putting on a YHM 3 lug adaptor. The adapter would not thread on due to the body being too small. So the value of the suppressor is great until you have to account for mounting it to your actual weapon. My weapon is 9mm with a 1/2×36 thread and JK does not make a taper mount for this size. I did order the 3 lug adapter directly through JK and the shipping was ridiculous and the wait is longer than it took the atf to approve. I want to get a piston system for a pistol but afraid I will have the same issue. Knowing what I do now I would have gone with an option which has compatible hardware or easily accessible hardware. Since the after costs of installing the suppressor are not figured into the equation.

Marksman gun range made everything so easy paperwork and purchase

No usability without there direct mounts but all there mounts are expensive and allways out of stock…should have spent little more for one that’s at least usable right out the box… also on top of usability is no live support and callbacks take months

Works well on my 9mm PCC. Not the quietest suppressor but it does a good job for the price. It also runs very cool compared to other cans. So it works very well when you put it under a handguard
