Silencer Co Piston 9/16×24 | Osprey/Octane

This piston is designed for use with SilencerCo Osprey and Octane series suppressors to provide a threaded interface between the host firearm and the silencer. Constructed from 17-4 stainless steel and heat-treated, it is intended to be user-replaceable so one suppressor can be adapted to different host firearms or subcaliber setups. The piston contains the female threading that mates to compatible threaded barrels and is a component of the Nielsen-style mechanism used on many autoloading pistols.
