SilencerCo AC860 Threaded Barrel 9mm Luger 5.80" 1/2x28 Black Nitride 416R Stainless - Fits Glock 34 Gen 1-4

The SilencerCo AC860 is a precision 9mm Luger threaded pistol barrel engineered as a drop-in replacement for the Glock 34 Gen 1-4. Slide the AC860 into an existing Gen 1-4 Glock 34 slide and the host is immediately suppressor-ready, with the correct thread pitch to mate with a 9mm pistol silencer.

The barrel is machined from heat-treated 416R stainless steel - a stainless grade widely used for match-grade pistol barrels - and finished in a low-reflectivity black nitride coating that boosts surface hardness and corrosion resistance while standing up to repeated suppressor use. Overall length is 5.80", and the muzzle is cut with the standard 1/2x28 thread pattern used by most 9mm pistol suppressors.

Designed specifically for use with a pistol silencer, the AC860 carries no integrated sights and relies on the slide-mounted sights of the host Glock 34. A thread protector is included to shield the crown and threads when a suppressor is not mounted.
