The JK Armament JK 155 Booster/3 Lug Adapter in 1.180-24 TPI is a precisely manufactured thread adapter ring that lets a pistol booster or 3 Lug mount run on a JK 155 suppressor (JK Armament part no. JK-155-LTA80). It adapts the mount to the industry-standard 1.375×24 TPI HUB thread, so it also works with other HUB-threaded suppressors. It is machined from T6-7075 billet aluminum, finished in black Type 3 hard anodize, and weighs just 0.5 ounce. This listing is the 1.180-24 TPI size, one of three internal thread sizes JK Armament offers so the ring matches the booster or 3 Lug mount you already own.

Key Specifications

• The internal thread is 1.180-24 TPI, the size that must match your booster or 3 Lug mount.
• The outside thread is the industry-standard 1.375×24 TPI HUB, which suits the JK 155 and other HUB-threaded suppressors.
• The material is T6-7075 billet aluminum, a strong, light alloy for a ring that carries a mount.
• The finish is black Type 3 hard anodize, a hard coating for a part that gets installed and removed.
• The ring has a 1.55-inch diameter, a compact size that adds little to the suppressor rear.
