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 4.4 ounces in its micro configuration and just 12.8 ounces in its full configuration, the 155 SBRX won’t weigh you down or affect the balance of your rifle.
Configurable from 3.3 inches to 6.5 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 hard use on 5.56 through .30 Cal rifles and short-barreled rifles.
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 refines the 155 SBRX’s sound signature for a solid, deep tone that’s more pleasing to the ear.
A lightweight, highly durable, Mission Configurable suppressor, the JK 155 SBRX is designed for heavy-duty use on bolt-action, semi-auto, and full-auto firearms, even with short barrels. Employing a 17-4 PH stainless steel blast baffle combined with four, user-configurable Grade 5 Titanium billet modular baffles delivers heavyweight durability in a lightweight silencer.
In its micro configuration, the 155 SBRX is 3.3 inches long and weighs a shockingly light 4.4 ounces. In its full configuration with all five baffles, it’s still only 6.6 inches long and weighs just 12.8 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? Clearing rooms with an M4? Run the 155 SBRX 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 SBRX 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 PRO 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.
The JK 155 SBRX is rated for cartridges up to and including 300 Win Mag while also being optimized to sound and work great on 223/5.56. It’s full-auto and short-barrel rated. See the Barrel and Caliber Ratings chart below for more information.
