The 155 PCX Suppressor from JK Armament is a highly modular, mission-adaptable suppressor designed to handle a variety of pistol and rifle calibers up to .45 caliber. With its tool-free design, it can be configured in multiple lengths—from ultra-compact 3.3″ to full-length 8.7″—to meet different performance and weight goals.
Constructed from Grade 5 titanium and 7075 aluminum, the suppressor weighs just 3.7 oz in micro form and about 11 oz fully assembled. The design includes a removable blast baffle, modular core baffles, and removable end cap, all housed in a durable black finish.
It uses a universal 1.375×24 HUB mount, making it compatible with a wide range of mounting systems and accessories. The JK 155 PCX is full-auto rated for select calibers and optimized for suppressed pistols, PCCs, and short-barreled rifles.
