SilencerCo AC2603 3-Lug Muzzle Device 45 ACP 5/8x24 Black

The SilencerCo AC2603 3-Lug Muzzle Device is a purpose-built steel adapter that threads onto a host .45 ACP barrel with 5/8x24 threads, providing a secure mounting interface for any suppressor equipped with SilencerCo's 3-Lug Mount. Finished in a low-glare matte black, it adds minimal length and weight to the host pistol while delivering a fast, tool-less attach-and-detach experience with 3-Lug-equipped suppressors.

This compact adapter installs directly onto a .45 ACP barrel with 5/8x24 threads, converting the threaded muzzle into a male 3-Lug pattern. Once in place, the suppressor indexes onto the three lugs and locks in with a quick quarter-turn, making range swaps between hosts and quick suppressor changes fast and repeatable. It is designed for use with any SilencerCo 3-Lug Mount equipped suppressor.

Built from steel with a corrosion-resistant matte black finish, the AC2603 is rated for the pressures and heat of .45 ACP use. The 5/8x24 thread pitch is the standard cut found on many .45 ACP pistol barrels, giving shooters a clean mounting solution with no permanent modification to the host firearm.
