A piston, sometimes called a Nielsen device, screws into the back of a pistol suppressor. Most pistol barrels tilt as the action cycles, and the weight of a suppressor can stop that. The piston adds a spring between the suppressor and the barrel so the pistol keeps cycling. Match the piston's thread to your pistol's barrel.
This one fits suppressors that take the SeaFire Diamond Piston and barrels threaded M13.5x1LH.
