Designed to be the lightest fully modular rifle suppressor on the market at the best possible price point, the JK 155 VERSAX .30CAL delivers leading sound suppression for sporting use. 



Fully modular length, suppression level, mounting solutions, and end caps to match your firearm and your mission. Convenient cleaning and maintenance without specialized tools.



An incredibly lightweight 3.7 ounces in its micro configuration and just 9.3 ounces in its full configuration, the 155 VERSAX .30CAL won’t weigh you down or affect the balance of your rifle.



Configurable from 3.3 inches to 7.3 inches long so you can choose the balance of length, weight, and sound suppression that’s right for your gun and your mission.



Threaded in the industry-standard HUB 1.375×24 mount pattern for maximum compatibility, including with our own selection of QD and direct thread mounts. Designed for sporting use on bolt-action and semi-automatic rifles from 5.56 and 300 Blackout up to magnum cartridges like 300 Win Mag.



There’s quiet on a dB meter, and then there’s quiet to the ear. With JK Armament’s Tone Technology you get both! Tone Technology plus the included Tone Tuner refine the 155 VERSAX .30CAL’s sound signature for a solid, deep tone that’s more pleasing to the ear.


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 five, 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.


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 five baffles and the Tone Tuner, it’s still only 7.3 inches long and weighs just 9.3 ounces. By simply adding or removing baffles and/or moving around or removing the Tone Tuner – 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 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, tri-lug mounts, QD mounts, pistol boosters, and much more, 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. See the Barrel and Caliber Ratings chart below for more information.
