The JK Armament Booster Piston is precision machined from 17-4 PH stainless steel and treated with a nitride finish for exceptional durability, corrosion resistance, and surface hardness. This essential component threads directly onto your pistol's threaded barrel, securely mating the suppressor and pistol together for reliable, consistent performance. Featuring a 1/2"x28 thread pattern, this piston is compatible with nearly all 9mm pistols and select other calibers sharing the same thread pitch. Engineered by JK Armament to exacting tolerances, this booster piston is an ideal choice for shooters building or upgrading a suppressor host setup.
