The JK Armament Pro-Kor 9K Ti in Armor Black is a 9mm suppressor 3D printed from Ti-6Al-4V Grade 5 titanium for pistol caliber carbines and subgun-style platforms (JK Armament part no. JK-172PRO-KOR9-K-TI). Its internal flow path is built to manage gas, flash and back pressure in a short 5.75-inch package, and it ships with a titanium three-lug mount. The Armor Black finish matches black carbines and pistol-caliber builds. A user-serviceable end cap lets the owner maintain it and change its configuration. It is a light, full-auto rated 9mm can for range days, competition and training.
