$52.25
The JK Armament JK155LTA25 is a 155 mm lightweight booster and 3-lug adapter designed for shooters who need a reliable interface component for suppressor systems. This aluminum adapter features 1.125x28 TPI threads, making it compatible with suppressors and devices using that standard thread pattern. Built from aluminum in a black finish, the JK155LTA25 combines the booster function with 3-lug mounting capability in a single compact component — useful for setups where you need both suppressor attachment options or are transitioning between different mounting systems on your firearms.
The 1.55-inch diameter of this adapter provides solid material mass while keeping overall weight down compared to steel alternatives. Whether you're running a precision rifle, an AR platform, or another firearm where suppressor interface flexibility matters, having a quality booster/adapter on hand means you're not locked into a single mounting method. JK Armament components are built with the precision and durability shooters expect for sound suppression and muzzle device applications.
This is a technical component best suited for shooters who already understand suppressor mounting systems and thread patterns. If you're building a modular suppressor setup or need a backup adapter for different firearms in your collection, the JK155LTA25 delivers straightforward functionality without unnecessary complexity or expense.

Frequently Asked Questions
What suppressors and devices work with 1.125x28 TPI threads?
The 1.125x28 TPI is a standard thread pattern used on many suppressors and muzzle devices. Check your suppressor or device documentation to confirm it uses this thread pitch before purchasing.
Can I use this adapter on multiple firearms?
Yes — as long as each firearm has a muzzle threaded to 1.125x28 TPI, you can move this adapter between them. It's useful for maintaining flexibility in a multi-gun collection.
What's the difference between the booster and 3-lug functions?
This component combines both in one piece: the booster function and the 3-lug mounting interface. That means you have mounting flexibility without carrying multiple separate adapters.
Is this a direct suppressor mount or an adapter?
This is an adapter and booster component. It interfaces between your firearm's muzzle threads and your suppressor or other muzzle device, and includes both booster and 3-lug mounting capability.
