This SilencerCo Piston is designed for reliably running a suppressor on your pistol. Without a piston and Nielsen device on your setup, the added weight of the suppressor can prevent the barrel from unlocking and fully cycling. With a piston and Nielson device attached it increases pressure allowing the barrel to unlock and reliably cycle the action. This SilencerCo Suppressor Piston is interchangeable with 9mm and .45 caliber SilencerCo suppressors and is threaded .578x28. It is machined from 17-4 stainless steel and heat treated for long term durability. Ensure your pistol and silencer setup are running smoothly with a SilencerCo Piston.

Compatible with:
  • Omega K Series
  • Hybrid 46

  • Octane Series

  • Heat treated 17-4 stainless steel
  • Threaded .578x28
  • Compatible with fixed barrel spacers
  • Interchangeable between 9mm and .45 caliber suppressors
