Why Pistol Boosters Matter
Many short-recoil pistols need the barrel to move during cycling. A compatible spring-loaded booster allows the suppressor and barrel to move appropriately relative to one another, helping the pistol complete its operating cycle. The correct mounting system depends on the firearm; a spring-loaded pistol booster should not be assumed suitable for a fixed-barrel carbine.
Steel Housing With a Lightweight Cap
The housing uses 17-4 PH stainless steel with a 7075-T6 aluminum cap. The raw heat-treat version retains the uncoated heat-treated appearance. The assembly adds approximately 0.43 inch to the suppressor length.
HUB Threads and Internal Clearance
The suppressor connection is 1.375x24 HUB and requires approximately 1.8 inches of internal clearance. Those dimensions should be checked together; matching HUB threads alone does not ensure room for the booster inside the suppressor.
Choose the Correct Piston
A .578x28 piston for .45 caliber / 10mm is included. The barrel must have that exact thread pattern, and the suppressor must be rated for the cartridge.

Frequently Asked Questions
What components are included?
The HUB piston-mount assembly and a .578x28 piston. The suppressor is separate.
Will it fit every pistol suppressor?
No. Use the compatible JK piston system and verify the suppressor interface, internal clearance, bore rating, and host firearm requirements.
Can caliber alone identify the correct piston?
No. A barrel's actual thread pattern must match the piston. Pistols in the same caliber can use different muzzle threads.
