SilencerCo AC2605 3-Lug Muzzle Device 45 ACP .578x28 Black

The SilencerCo AC2605 is a 3-Lug muzzle device designed to thread onto .45 ACP pistol barrels with a .578"x28 thread pitch, providing a secure mounting interface for a SilencerCo 3-Lug suppressor mount. This compact adapter lets shooters quickly attach and detach a compatible suppressor without swapping tools at the range.

Machined from steel and finished in a low-reflectivity black coating, the AC2605 is built to handle the recoil and blast of .45 ACP host firearms. The three-lug design creates a positive, repeatable lockup with the mating 3-Lug mount (sold separately), delivering a tight, concentric seal that keeps your suppressor aligned shot after shot.

Installation is straightforward: thread the device onto any .45 ACP barrel with matching .578"x28 threads, then attach your SilencerCo suppressor using the compatible 3-Lug mount. The result is a quick-detach setup well suited for pistol-caliber hosts and pistol-caliber carbines running .45 ACP.
