SilencerCo AC26 Osprey/Octane Piston M13.5x1 LH 9mm Stainless Steel

The SilencerCo AC26 Osprey/Octane Piston is a factory replacement piston for SilencerCo's Osprey and Octane suppressors, machined from rugged 17-4 stainless steel and purpose-built for 9mm Luger handgun hosts fitted with an M13.5x1 LH (left-hand) threaded barrel.

Both the Osprey and the Octane use SilencerCo's modular piston system, allowing the end user to adapt the suppressor to different barrel thread specifications without permanent modification. The AC26 carries a left-hand thread pattern so the piston resists loosening under the vibration and pressure of repeated semi-auto fire, keeping the can locked up tight to the host barrel.

Finished in a natural stainless finish and carrying SilencerCo MPN AC26, this piston is the correct swap-in for shooters running an Osprey or Octane on a 9mm pistol with an M13.5x1 LH thread pattern.
