JK 155 VERSAX .30cal silencer

An extraordinarily lightweight, Mission Configurable suppressor, the JK 155 VERSAX .30CAL is designed for sporting use (see Barrel and Caliber Ratings chart below) on bolt-action firearms and for limited semi-auto use. Employing six, user-configurable 7075 billet modular baffles keeps weight to an absolute minimum while providing solid sound suppression performance along with JK’s pleasing Tone Technology sound.

In its micro configuration, the VERSAX .30CAL 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 9.3 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.

Out on a long hunt, carrying your rifle for hours on end but, if all goes to plan, only shooting once? Run the 155 VERSAX in a shorter configuration to reduce weight and maximize maneuverability. Spending some time on the range shooting steel targets at a distance? Stack up the baffles for maximum sound suppression.

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 direct thread fixed mounts and QA mounts, the versatility of the HUB standard can’t be overstated.

A .30 caliber suppressor, the JK 155 VERSAX .30CAL is rated for cartridges up to and including 300 Win Mag. The barrel length and rate of fire restrictions apply depending on the cartridge.

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!

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!
