JK Armament JK155 HD Direct Thread Mount .578x28 Stainless Steel Cerakote Black

The JK Armament JK155 HD Direct Thread Mount is a heavy-duty suppressor attachment machined from 17-4 stainless steel and finished in a durable Cerakote black coating. Designed to securely mate JK 155 series suppressors to host barrels with a .578x28 thread pitch, this mount combines rugged construction with straightforward, tool-friendly installation.

On the barrel side, the JK155 HD features a .578x28 thread pattern that threads directly onto the host firearm's muzzle. The suppressor side accepts the industry-standard HUB 1.375-24 (1-3/8x24) TPI interface, so the mount pairs cleanly with all JK 155 suppressors and other HUB-compatible cans. With a 1.55" outer diameter, the mount provides a solid shoulder surface for repeatable lockup and proper concentric alignment shot after shot.

Heat-treated 17-4 stainless steel construction gives the JK155 HD the toughness to handle heavy-recoil magnum and large-bore cartridges, while the Cerakote finish shields the steel from corrosion, carbon, and handling wear. Whether you run a JK 155 for precision, hunting, or hard-use applications, this direct thread mount installs securely, removes easily for cleaning or swap-out, and delivers the same locking geometry every time it goes on.
