{"product_id":"griffin-universal-piston-griffin","title":"Griffin Armament Universal Piston – Multi-Caliber Pistol Suppressor Adapter","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eMachined 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Suppressor Booster Piston\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Tilting-barrel semi-automatic pistols\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-treated stainless steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Black nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Griffin Armament modular suppressor systems with appropriate Nielsen device\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Use of this product with a suppressor requires compliance with NFA regulations.
