Griffin Armament Piston Barrel Adapter 1/2x28 – Pistol Caliber Suppressors

The Griffin Armament Piston Barrel Adapter converts fixed-mount suppressors to Nielsen device (booster) systems for reliable cycling on tilting-barrel pistols. This adapter threads onto 1/2x28 barrels and accepts Griffin pistons, allowing you to run pistol-caliber suppressors on firearms that require a recoil booster for function. Essential for most browning-style actions in 9mm and other pistol calibers.

Machined from hardened steel with a corrosion-resistant finish. Installs hand-tight with witness marks for proper timing. Compatible with Griffin Armament suppressor systems that use interchangeable piston assemblies. Verify your suppressor and firearm compatibility before ordering—not all suppressors require or accept piston adapters.
