Griffin Armament Universal Piston – Multi-Caliber Pistol Suppressor Adapter

The Griffin Armament Universal Piston is a booster assembly component that enables proper cycling of tilting-barrel semi-automatic pistols when using a suppressor. This piston threads onto your pistol's barrel and couples with Griffin's modular suppressor systems, allowing the barrel to recoil independently while the suppressor remains forward—essential for reliable cycling with added backpressure.

Machined from heat-treated stainless steel with a black nitride finish for corrosion resistance and durability. The universal designation means this piston is compatible with multiple thread pitches when paired with the appropriate Nielsen device and suppressor mount. Installation is straightforward: thread the piston onto your barrel, install the booster spring and Nielsen device per your suppressor's instructions, and attach the suppressor. Verify proper fit and function before live fire.
