The CGS Suppressors CGSKRK135X1LHBK Piston M13.5x1 LH Black Nitride 17-4 Stainless Steel is a precision-machined mounting solution for CGS Kraken, MOD9, and Nautilus series suppressors. Built from durable 17-4 stainless steel with a black nitride finish, this piston uses an M13.5x1 left-hand thread pattern to provide secure, repeatable attachment to compatible 9mm barrels while supporting smooth, reliable suppressor function.

Designed for shooters who demand consistent performance from their suppressed setups, this self-aligning piston helps maintain proper bore alignment and reduces the risk of baffle strikes. Its positive spoke lock interface keeps the suppressor firmly seated during extended range sessions or training, making it a dependable choice for enthusiasts who regularly run CGS pistol-caliber silencers.
