SilencerCo AC728 Osprey/Octane Piston Kit 5-Piece Stainless Steel - Black Nitride

The SilencerCo AC728 is a complete 5-piece piston kit engineered for the Osprey and Octane pistol suppressors. Every piston is machined from stainless steel and finished in black nitride for long-term wear and corrosion resistance at the host's muzzle interface. With five pistons in a single package, the kit lets one suppressor user swap between multiple host firearms of varying barrel thread patterns without buying each piston separately.

The set ships with pistons in the most common mounting threads for the Osprey and Octane lineup - including .578x28, 1/2x28, and 16mm x 1 LH - along with three O-ring packs to keep each piston properly sealed inside the suppressor body. The black nitride finish blends with the suppressor housing for a clean, factory appearance.

This is a brand-new, factory-supplied SilencerCo accessory kit and the simplest way to keep a full rotation of pistons on hand for any host your Osprey or Octane will run on.
