The CGS Suppressors CGSKRK12X28PISTBK Piston 1/2"-28 Tpi Black Nitride 17-4 Stainless Steel is a dedicated 9mm mounting piston engineered for Kraken, MOD9, and Nautilus series suppressors. Machined from durable 17-4 stainless steel and finished in black nitride, it offers a precise 1/2"-28 thread interface and a robust spoke-lock design that secures the piston within the suppressor housing.

This piston is ideal for shooters who run threaded-barrel pistols or pistol-caliber carbines and want reliable suppressor attachment with consistent alignment. Its self-aligning system helps maintain accuracy and smooth cycling during extended range sessions or training days, while the compact 2" length and 1" diameter keep overall weight and bulk to a minimum. Backed by CGS Suppressors’ reputation for thoughtful engineering and refined suppressor accessories, it is a practical upgrade for any compatible 9mm host.
