A Grade 5 Titanium JK 155 PRO blast baffle and seven user-configurable 7075 billet JK 155 LT modular baffles combine for an ideal balance of strength and weight. JK’s Tone Technology delivers industry-leading sound reduction along with a solid, deep tone that’s more pleasing to the ear.

In its micro configuration, the PCX .45cal is 3.3 inches long and weighs a shockingly light 3.7 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 are needed! – the user is able to choose the length, weight, and sound suppression that’s right for the firearm and the mission.

The JK 155 PCX .45cal is rated for .45cal full-auto use as well as for use on other pistol calibers from 25 ACP on up to 357 Magnum, and even on 300 Blackout, all without barrel length restrictions. It can even be used on rifles chambered in 223/5.56, 350 Legend, 308 Win, 300 Win Mag, and more with varying barrel length requirements. This makes the 155 PCX an extremely versatile choice!

In addition to the modular baffle and end cap design, the 155 PCX 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 pistol boosters, direct thread fixed mounts, tri-lug mounts, QD mounts, and much more, the versatility of the HUB standard can’t be overstated.
