JK Armament Piston .45 Caliber .578x28 Black Nitride Stainless

Jk Armament Piston Features The Jk Armament Piston is precision machined from 17-4 PH stainless steel a material chosen for its strength and corrosion resistance under the repeated cycling a booster piston experiences in a suppressed pistol system. The piston screws directly onto a threaded pistol barrel forming the mechanical link between the firearm and a compatible suppressor s booster mechanism. Sized for .578x28 threads this piston is built for .45 Caliber and other pistol calibers larger than 9mm a size class with its own dedicated thread standard separate from the common 1/2x28 pattern used on smaller bores. At a 1.55 inch diameter the piston is sized to integrate cleanly with JK Armament s suppressor lineup. A black nitride finish protects the piston s surface from wear and corrosion while standing up to the heat and fouling generated during suppressed fire. Because the piston is a wear component in the suppressor s moving booster system its stainless steel construction is intended to provide long service life under repeated use. JK Armament offers this piston specifically for pistol applications distinguishing it from piston variants built for rifle calibers or different thread patterns. For shooters running a .45 caliber suppressed pistol setup the Jk Armament Piston provides the correct mounting hardware to keep the system cycling reliably.
