Primary Weapons PWS Suppressor Piston .578x28 Thread Black
The PWS Suppressor Piston is a drop-in replacement piston machined from 17-4 stainless steel, built to keep a suppressed pistol running through extended range sessions. Its .578x28 thread pitch matches common large-bore pistol hosts, and the piston swaps out quickly so the same suppressor can move between firearms and calibers.
It is compatible with PWS BDE 9, Rugged, SilencerCo, Lone Wolf Arms, and Griffin pistol suppressors, giving shooters a single spare part that covers several suppressor systems. The black finish keeps the assembly visually consistent with the rest of the can.
