SilencerCo AC30 Osprey/Octane Piston 30 Cal 5/8x24 Stainless Steel

The SilencerCo AC30 is an interchangeable silencer piston designed to mount the company's Osprey and Octane suppressors onto host handguns with a 5/8"x24 right-hand barrel thread. Machined from 17-4 stainless steel with a corrosion-resistant stainless finish, the AC30 is built to handle the repeated slide-on, slide-off cycling that pistol-caliber piston mounts see every time the host is brought up on target, and is recommended for use with .30 caliber handgun hosts.

SilencerCo's piston system lets the end user run a single Osprey or Octane can across multiple host firearms and calibers simply by swapping pistons. Because the AC30 threads directly into the host barrel rather than relying on a separate muzzle device, installation is straightforward with basic hand tools, and the rugged 17-4 stainless construction stands up to regular field use without concern for thread galling or finish wear. The AC30 is the 5/8x24 model in the Osprey/Octane piston family and serves as a direct OEM replacement or spare for any shooter running that suppressor platform.
