The JK Armament PRO-KOR 6 Mini Ti suppressor is a compact, ultra-lightweight titanium can for 5.56 and 6 ARC rifles. JK built it from the proven 556K platform and shortened it to 4.8 inches and 8 ounces without the mount, for shooters who want low back pressure and strong sound performance without extra length. The 3D-printed titanium body takes a HUB 1.375-24 mount, and the included War Eagle muzzle device gives a secure, repeatable mounting interface. This version is finished in FDE Cerakote. It is a natural fit for a duty carbine, a lightweight recce rifle or a compact SBR.

Key Specifications

• Length is 4.8 inches without the mount and 5.2 inches with it, a very short can for its class.
• Weight is 8 ounces without the mount and 9.6 ounces with it, which keeps a short rifle nimble.
• Diameter is 1.72 inches, the profile that sets how much room it takes on the muzzle.
• The suppressor and mount are Ti-6Al-4V Grade 5 titanium, a high strength-to-weight material.
• It is full-auto rated for 5.56mm on barrels 10.3 inches or longer, with a 14.5-inch minimum for 6mm ARC, 6mm MAX, .22 Creedmoor and .22 ARC.
