Jk Armament HD Direct Thread Mount Features The Jk Armament HD Direct Thread Mount uses the industry standard HUB 1.375-24 TPI thread pitch on the suppressor side a widely adopted standard that works with all JK 155 suppressors as well as dozens of suppressors from other manufacturers. This broad compatibility gives shooters flexibility to mount a variety of suppressor models onto the same firearm without needing a different mount for each can. On the firearm side the mount is machined to the .578x28 thread pitch one of several thread sizes Jk Armament offers to match factory muzzle threads across different platforms. Constructed from stainless steel the mount is built to withstand the heat and repeated mounting cycles that suppressor use demands. A black Cerakote finish protects the stainless steel body from corrosion while giving the mount a durable low-glare appearance that matches most black firearm finishes. At 1.55 inches in diameter the mount is sized to handle the loads generated during suppressed fire without excessive bulk at the muzzle. This direct thread design offers suppressor owners a straightforward no-frills mounting solution compared to more complex quick-detach systems. For shooters running JK 155 or other HUB-compatible suppressors the Jk Armament HD Direct Thread Mount is a dependable precisely machined connection point.
