B&T Firearms Alpha Piston 1/2x28 Stainless Steel Suppressor Piston

The B&T Alpha Piston is a precision-machined suppressor piston designed to mount on 9mm pistol barrels with a standard 1/2x28 thread pattern. Manufactured from durable 17-4 stainless steel, this piston is built to handle the heat, gas, and recoil of repeated semi-automatic fire while maintaining a tight, reliable seal between the piston body and the host suppressor bore.

The Alpha Piston threads directly onto the muzzle of a 9mm Luger barrel and provides the mounting interface between the host pistol and a compatible suppressor. Designed for use with B&T suppressors and other major pistol-caliber silencers, this piston is a quality replacement or spare for shooters running a B&T-equipped pistol setup.

Finished in a natural stainless steel finish and made in the USA, this piston matches the standard 1/2x28 thread pitch found on most 9mm pistol barrels.
