SilencerCo Piston 1/2×28 XL | Osprey/Octane

The SilencerCo piston 1/2×28 XL is an extended female-thread piston made for the Osprey and Octane family of suppressors. It is manufactured from 17-4 stainless steel and heat treated for long-term durability. The piston is part of the Nielsen device used on many semi-automatic pistols to allow proper cycling and contains the female threads that attach to SilencerCo threaded barrels. The XL length provides additional spacing where the suppressor requires extra distance from the host muzzle.
