JK Armament 155 LT Booster/3 Lug Adapter 1.180x24 TPI Black Aluminum - 1.55" Diameter

The JK Armament JK155LTA80 is a booster and 3-lug adapter built for the JK 155 LT suppressor family. The assembly threads onto the suppressor body at 1.180x24 TPI and presents a 3-lug quick-detach interface on the muzzle side, allowing semi-automatic pistol platforms to cycle reliably with a suppressor mounted.

The unit is constructed from aluminum and finished in hard anodized black for corrosion resistance and durability through repeated mount and dismount cycles. It measures 1.55" in diameter and is purpose-built as a direct-fit booster/3-lug for the JK 155 LT suppressor series.

Installation is straightforward: thread the 1.180x24 TPI side into the rear of a compatible JK 155 LT suppressor body, then drop the 3-lug interface into any host pistol barrel fitted with the matching 3-lug pattern for a secure, quick-detach mount.
