SilencerCo Threaded Barrel for Glock 22 Gen 2-4, 40 S&W, Black Nitride Stainless

The SilencerCo threaded barrel (brand part number AC50) gives the Glock 22 Gen 2-4 a factory-correct 40 S&W barrel with 9/16×24 muzzle threads, built for shooters who want to run a pistol suppressor. Every pistol suppressor needs a threaded host barrel, and SilencerCo built this one to the same standard of quality as the rest of its lineup, machined from 416R stainless steel and finished in black nitride to handle harsh conditions. A thread protector ships with the barrel to keep the threads clean when no device is mounted, though note that running a pistol silencer will also require a separate piston, sold separately. For Glock 22 owners looking to add suppressor compatibility, this barrel is the first purpose-built piece of that setup.
