The JK Armament Pro-Kor 6 Mini Ti in black is a compact 3D-printed titanium rifle suppressor for 5.56mm and 6mm ARC rifles. JK Armament built it from the proven Pro-Kor 5.56K platform and trimmed it to a 4.8-inch tube that weighs 8 ounces without the mount. It is aimed at duty carbines, lightweight recce rifles and compact SBRs where every ounce counts. The War Eagle muzzle device is included, and the tube is compatible with the industry-standard HUB 1.375-24 mount pattern. The Armor Black Cerakote finish keeps it low profile on a dark rifle.
