The Advanced Armament Corp (AAC) Suppressor Piston significantly enhances the versatility of your NFA setup, allowing your silencer to transition effortlessly across multiple host platforms with varying barrel threads. Purpose-built as a direct replacement component for the legendary Ti-RANT 9 and EVO-9 sound suppressors, this piston features an M13.5x1LH thread pattern, making it a precise match for European-style metric pistol barrels. Operating as a critical component of the Nielsen booster device, it allows the suppressor to move independently of the barrel during the firing cycle. This design ensures consistent slide cycling and flawless semi-automatic reliability on tilting or reciprocating barrel platforms. Machined from heat-treated stainless steel with a bead-blasted matte finish, each piston is deeply engraved with the thread diameter, pitch, and rotational direction for quick identification and fail-safe installation.

Please Note: This booster piston is explicitly designed for legacy Ti-RANT 9 and EVO-9 models. It is not compatible with and will not work with the newer AAC Ti-RANT 9M-HD series silencers.
