Silencerco Osprey, Octane, Omega 9K & Omega 45K Pistons


The Osprey and Octane family of suppressors have pistons that are easily changed for different host weapons or sub-calibers. Pistons are constructed from 17-4 stainless steel and then heat treated for maximum durability. The piston is part of the Nielsen device that moves and allows semi-automatic cycling, but it also contains the female threads that attach to the muzzle of the host pistol or sub-gun. These pistons are easily interchangeable for compatibility with all relevant host guns and can be changed out to be compatible with sub-caliber host guns, which means you can shoot smaller caliber rounds through the same suppressor, making it a multi-caliber silencer.

Works on all Octane and Osprey Suppressors as well as Omega 9K and Omega 45K
