Yankee Hill Machine Company Sidewinder Piston 40SW 14.5x1L – Threaded Suppressor Mount

The Yankee Hill Machine Company Sidewinder Piston is a threaded mount designed for use with compatible Sidewinder suppressors on firearms chambered in .40 S&W and similar calibers. This piston uses a 14.5x1mm left-hand thread pitch, allowing secure attachment to barrels threaded in this specification. The piston system creates a sealed interface between the suppressor and barrel, facilitating proper function in tilting-barrel pistol designs.

Constructed from heat-treated steel for durability under sustained firing schedules, this piston is precision-machined to ensure consistent lockup and alignment. Compatible with firearms that utilize 14.5x1mm left-hand threading, commonly found on certain European and aftermarket barrels. Verify your barrel's thread pitch before ordering.
