Product Description The SilencerCo AC861 Threaded Barrel is a premium drop-in replacement barrel designed specifically for the Glock 17L chambered in 9mm Luger. Engineered to the same exacting standards as all SilencerCo products, this barrel is constructed from 416R stainless steel and finished in a durable black nitride coating that dramatically improves surface hardness and corrosion resistance. The 6.50" barrel features 1/2"x28 muzzle threads, making it fully compatible with a wide range of pistol suppressors and muzzle devices. Designed to fit Glock 17L Gen 1-4 pistols, it comes with a thread protector to safeguard the threads during unsuppressed use. Note that for use with a pistol silencer, a compatible piston is also required.
