SilencerCo AC2024 S&W M&P 45 ACP 5.10" .578x28 Threaded Barrel Black Nitride

The SilencerCo AC2024 is a precision-machined replacement threaded barrel for the Smith & Wesson M&P full-size pistol chambered in 45 ACP. It is cut from 416R stainless steel and finished in a durable black nitride coating, giving the bore and exterior a tough, corrosion-resistant surface that holds up under the heat demands of repeated suppressed fire.

Measuring 5.10" overall, the AC2024 is fitted with .578x28 threads at the muzzle, ready to accept a .45 ACP-rated pistol suppressor. The barrel ships without sights and is designed to drop into the S&W M&P slide as a direct replacement for the factory barrel. The black nitride finish provides a wear-resistant surface that matches the factory S&W profile.

Whether you are running an Omega 36M, Hybrid 46, or another .45 pistol can, the SilencerCo AC2024 delivers the correct thread pitch and a robust 416R stainless steel build to get the most out of your suppressor on a full-size M&P.
