JK Armament 155 LT Booster/3-Lug Adapter 1.203x28 TPI Black Aluminum

The JK Armament 155 LT Booster/3-Lug Adapter is a precision-engineered suppressor accessory that merges a booster assembly with a 3-lug quick-detach mount in a single, lightweight component. It is designed to give a pistol-caliber suppressor reliable function with semi-auto hosts while providing a durable 3-lug attachment point for fast, secure suppressor swaps.

Machined from aluminum and finished in a low-glare hard anodized black coating, the adapter measures 1.55" in diameter and weighs just 0.50 oz, keeping overall host-plus-suppressor weight to a minimum. Threaded 1.203x28 TPI, it mates with hubs such as the Dead Air Key Micro and other compatible 1.203x28 mounting interfaces for a precise, repeatable lock-up between suppressor and host.

Whether running a dedicated booster-equipped pistol-caliber setup or switching to a 3-lug configuration, the JK Armament 155 LT Adapter delivers a streamlined, lightweight mounting solution for modern suppressor use.
