LEDE RPX 30

JK Armament is proud to announce its all-purpose .30-caliber suppressor, the JK 155 RPX .30Cal.

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 Winchester, .357 Magnum and so many more all the way up to .300 Win. Mag. (minimum barrel lengths apply to some calibers). Or, run it on 223/5.56, 5.7×28, and other small calibers with a .22-caliber end cap.

An extraordinarily lightweight suppressor, the JK 155 RPX .30Cal combines the benefits of the RCX and PCX lines. A grade 5 titanium blast baffle combined with seven, user-configurable 7075 billet modular baffles delivers heavyweight durability in a featherweight silencer.
