Griffin Armament Piston Barrel Adapter – 9/16x24 Thread Pitch

The Griffin Armament Piston Barrel Adapter enables the use of Griffin's piston-based suppressor systems on barrels threaded 9/16x24. This adapter functions as an intermediary component in a Nielsen device (booster) assembly, allowing proper cycling of tilting-barrel pistols when a suppressor is mounted. Without a functional booster system, recoil-operated handguns often fail to cycle reliably under suppression due to the added weight and back pressure.

This adapter threads directly onto your barrel and accepts Griffin's interchangeable piston system. Constructed from heat-treated steel with a durable black nitride finish, it provides a secure mounting point while resisting carbon buildup and corrosion. Confirm your barrel's thread pitch before ordering—9/16x24 is less common than standard pistol threads and typically found on specific aftermarket barrels or particular firearm models.
