Primary Weapons Systems Piston Features The Primary Weapons Systems Piston is machined from 17-4 stainless steel a material chosen for its combination of hardness corrosion resistance and long-term durability under the heat and pressure a suppressor piston experiences. Built specifically to the .578x28 thread pitch it integrates with a range of popular pistol suppressors including PWS BDE 9 Rugged SilencerCo Lone Wolf Arms and Griffin models. This broad compatibility means a shooter is not locked into a single suppressor brand if their equipment changes over time. The piston s design is specifically engineered to integrate seamlessly with the PWS BDE 9 pistol suppressor for optimal performance and reliability. Because the piston is modular it can be swapped between different host firearms or calibers as the shooter s suppressor setup evolves providing real flexibility rather than a single-use fixed component. The black anodized finish resists wear and corrosion from repeated cycling and exposure to combustion byproducts near the muzzle. Reliable piston function is critical to a suppressor s performance since a worn or improperly fitted piston can affect both sound reduction and cycling reliability on a host pistol. For suppressor owners who need a durable adaptable replacement or upgrade piston the Primary Weapons Systems Piston is available for sale at GrabAGun.
