JK Armament, 155 RPX, 30 Cal, Modular Silencer, Black (JK-155RPX30)

Our best all-purpose .30 cal suppressor!

With its fully Mission Configurable design, advanced baffle geometry, and HUB mount threads, the JK 155 RPX .30CAL is ready to rock on all your favorite rifles and carbines. Super quiet and incredibly lightweight, the RPX .30CAL’s efficient baffles are bored to .36 caliber, so with just a quick end cap swap it can suppress 350 Legend, 338 ARC, 9mm pistols and carbines, and more.

An extraordinarily lightweight, Mission Configurable suppressor, the JK 155 RPX .30CAL combines the benefits of the RCX and PCX lines into our best all-purpose .30 cal suppressor ever! A grade 5 titanium blast baffle combined with seven, user-configurable 7075 billet modular baffles delivers heavyweight durability in a featherweight silencer.

With its .36 caliber bore and our most advanced baffle design that merges rifle and pistol suppression performance into a single suppressor, the 155 RPX .30CAL is ready for duty on pistols, carbines, rifles, machine guns, and more. With only a quick End Cap swap to handle anything larger than .30 caliber, the RPX .30CAL has you covered from 9mm to 350 Legend to 300 Blackout, 338 ARC, 308 WIN, 357 Magnum, and so many more all the way up to 338 Lapua (minimum barrel lengths apply to some calibers). Or, run it on 223/5.56, 5.7×28, and other small calibers with a .22 cal End Cap.

In its micro configuration, the 155 RPX .30CAL is 3.3 inches long and weighs a shockingly light 3.6 ounces. In its full configuration with all eight baffles, it’s still only 8.7 inches long and weighs just 11 ounces. By simply adding or removing baffles – no specialized tools needed! – the user is able to choose the length, weight, and sound suppression that’s right for the firearm and the mission.

In addition to the modular baffle and end cap design, the 155 RPX .30CAL 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 and other ASR-compatible 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.
