The SilencerCo Threaded Barrel Glock 21 allows accessories to be mounted at the end of your firearm. All pistol suppressors require a threaded pistol barrel.

Holding to the same commitment to quality as all of our products, the threaded barrels are tough enough to hold up under the harshest conditions. Made of 416R stainless steel and finished in black nitride.
