Primary Weapons Systems .578x28 Suppressor Piston Black

The Primary Weapons Systems Piston is a replacement suppressor piston machined from 17-4 stainless steel and cut to a .578x28 thread pitch. It is intended for owners of compatible pistol suppressors who need a durable, swappable piston for repair or upgrade.

The piston has a black anodized finish, which resists wear and corrosion from repeated cycling and exposure to combustion byproducts near the muzzle. Stainless steel was selected for hardness, corrosion resistance and long-term durability under the heat and pressure a suppressor piston sees.

The piston is listed as compatible with the PWS BDE 9 Rugged, SilencerCo Lone Wolf Arms and Griffin pistol suppressors. Because it is modular, it can be moved between host suppressors as a shooter's setup changes. Confirm fitment against your specific suppressor before ordering.
