SilencerCo AC2023 S&W M&P 9mm Luger 4.75" 1/2x28 Threaded Barrel - Black Nitride

The SilencerCo AC2023 Threaded Barrel is a drop-in replacement barrel for the S&W M&P 9mm series of pistols. Machined from 416R stainless steel and finished in a tough black nitride coating, this barrel adds suppressor-ready threading to your factory slide.

The 4.75" bore uses a 1:10 right-hand twist and is chambered for 9mm Luger. The muzzle is cut with a standard 1/2x28 thread pitch, allowing direct attachment of a pistol silencer using a SilencerCo piston (sold separately) or any other 9mm muzzle device with the matching thread pattern.

Designed as a direct-fit replacement for the factory M&P 9mm barrel, the AC2023 installs in seconds and brings the rugged black nitride finish to your pistol. The barrel ships ready to drop into a standard S&W M&P 9mm pistol.
