JK Armament 155 HD Direct Thread Mount, .578x28, Black
The JK Armament 155 HD Thread Mount connects a compatible suppressor directly to .578x28 barrel threads. It is a straightforward choice when a dedicated barrel connection is preferred over a separate quick-attach muzzle device.
The suppressor-side interface is 1.375x24 HUB. That second thread specification matters just as much as the barrel thread: the mount has to match both the firearm and the suppressor.

A Direct Connection at the Barrel
The mount replaces a compatible suppressor's rear mounting component and supplies the .578x28 barrel interface. A separate taper-mounted muzzle device is not required for the direct-thread connection. For a firearm that normally keeps the same suppressor attached, fewer mounting components can make equipment selection simpler.
Construction Suited to the Mounting System
Heat-treated 17-4 stainless steel provides a durable mounting body. The Armor Black C-192 Cerakote finish complements the steel construction, while 1.5-inch external wrench flats and an internal 3/4-inch hex provide tool engagement.
Barrel and Suppressor Compatibility
Use .578x28 on the barrel side and 1.375x24 HUB on the suppressor side. The HUB interface is widely used, but mounting depth, internal clearance, and the suppressor manufacturer's approval still matter. A direct-thread mount is not a spring-loaded pistol booster. The complete firearm and suppressor combination must support direct mounting; the mount alone does not establish caliber suitability.

Frequently Asked Questions
Is a separate muzzle device needed?
No taper-mounted muzzle device is required for the direct-thread connection. The barrel must already have the correct threads and mounting geometry.
Are barrel threads and suppressor threads the same?
No. This mount uses .578x28 at the barrel and 1.375x24 HUB at the suppressor.
Does the mount change the suppressor caliber rating?
No. The suppressor's bore, end cap, pressure rating, and firearm requirements still govern compatibility.
