The JK Armament 155HD Direct Thread Mount in 1/2×36 is the simplest, most direct way to attach a JK 155 suppressor to a barrel with a 1/2×36 muzzle thread (JK Armament part no. JK-155-HDM1236). On the suppressor side it uses the industry-standard HUB 1.375×24 thread, which works with all JK 155 suppressors and many from other makers. It is machined from heat-treated 17-4 stainless steel and finished in Armor Black Cerakote. A 3/4-inch internal socket drive and 1.5-inch outside wrench flats make it easy to torque down and just as easy to remove.

Key Specifications

• The muzzle-side thread is 1/2×36 TPI, matched to barrels with that factory thread.
• The suppressor-side thread is HUB 1.375×24 TPI, which fits every JK 155 suppressor and many other brands.
• The material is heat-treated 17-4 stainless steel, a tough alloy for repeated mounting.
• The coating is Armor Black C-192 Cerakote, a durable finish for the exposed ring.
• Weight is 2.1 ounces, so the mount adds little to the front end.
• Installation uses 1.5-inch external wrench flats and a 3/4-inch internal hex, for a secure fit and easy removal.
