Yankee Hill Machine Sidewinder Piston .45 ACP .578x28 – Suppressor Accessory

The Yankee Hill Machine Sidewinder Piston is a replacement or spare piston designed for use with YHM pistol suppressors chambered in .45 ACP. This piston enables the suppressor to mount securely to host firearms equipped with .578x28 threaded barrels, providing reliable function in recoil-operated pistol actions. The piston assembly allows the suppressor to decouple from the barrel during cycling, ensuring proper semi-automatic operation.

Constructed from durable materials to withstand repeated cycling and suppressor heat, this piston is engineered for consistent performance. It's designed specifically for YHM Sidewinder and compatible .45 ACP suppressors. Installation is straightforward—thread onto your barrel, then attach the suppressor to the piston mount.
