  • Features


Extremely lightweight and fully Mission Configurable, the JK 155 VERSAX 9MM suppressor is right at home on every 9mm in your collection, from handguns to full-auto subguns. At the same time, it’s stout enough for use on rifles chambered in 300 Blackout, 8.6 Blackout, 350 Legend, and many more.

Employing six, user-configurable 7075 billet modular baffles plus one JK 155 LT Tone Tuner keeps weight to an absolute minimum while providing solid sound suppression performance along with JK’s pleasing Tone Technology sound.

JK 155 PCX 9MM silencer

In its micro configuration, the VERSAX 9MM is 3.3 inches long and weighs a shockingly light 3.7 ounces. In its full configuration with all six baffles, it’s still only 7.3 inches long and weighs just 8.9 ounces. By simply adding or removing baffles – no specialized tools are needed! – the user is able to choose the length, weight, and sound suppression that’s right for the firearm and the mission.

JK 155 PCX 9MM silencer with Tri Lug Mount

In addition to the modular baffle and end cap design, the 155 VERSAX is even more Mission Configurable thanks to its industry-standard HUB 1.375×24 mount size. This means dozens of mounting options are instantly available! From the included JK 155 LT Quick Attach Taper Mount, which fits our industry-leading JK muzzle devices, to pistol boosters, direct thread fixed mounts, tri-lug mounts, QD mounts, and much more, the versatility of the HUB standard can’t be overstated.

The JK 155 VERSAX 9MM is rated for 9mm, 38 Special, and 357 Magnum full-auto use as well as for lighter duty use on 300 Blackout, 350 Legend, 223 Remington, 308 Winchester, 300 Win Mag, and many more pistol and rifle calibers making it a highly versatile choice. See the Barrel and Caliber Ratings chart below for barrel length restrictions and more information.

    • 2x .22 cal Bald Eagle
    • 2x .30 cal Bald Eagle
    • 1x 9mm Bald Eagle
    • 1x 1/2x28 Pistol Booster

With this build I can suppress every .30 caliber and smaller rifle and every 9mm and smaller pistol in my collection. Whether I’m running my AR-15 or AR-10 hard – even full-auto – or I’m on a spot-and-stalk hunt with a lightweight bolt-action rifle, or I’m plinking or varmint hunting with a rimfire rifle, or I’m shooting pistols and pistol caliber carbines in 9mm or smaller, this one suppressor can be configured so it’s ideally suited for each and every one of those things and more.

Heck, if I also owned a 45 ACP pistol and/or a 458 SOCOM rifle or a .45 cal lever action I could add 5x .45 cal LT and/or PRO Pistol baffles and have those guns covered, too!

  • 105 Series
  • LT base tube
  • Baffles:
    • 1x .22 cal HD Rimfire
    • 6x .22 cal LT Rimfire
    • 6x 9mm LT Pistol

  • End Caps:
    • 1x .22 cal LT Flash Reducer
    • 1x 9mm LT Flash Reducer
  • Mounts:
    • 1x 1/2x28 Thread Mount

With this build I can suppress all of my rimfire rifles and pistols plus anything in 5.7x28mm. It’s also a Mission Configurable 9mm pistol and PCC suppressor that’s capable of being run in a full configuration for training on the shooting range and a short configuration for concealed carry. It’s so lightweight that it doesn’t need a booster!
