The SilencerCo AC2605 3-Lug Muzzle Device is a purpose-built mount point for shooters running 45 ACP pistol suppressors. This .578"x28 threaded adapter screws directly onto your barrel and serves as the interface for SilencerCo's 3-lug suppressor mounts—a quick-attach system that lets you swap cans fast without tools. If you're building a suppressed 45 ACP pistol or want the flexibility to move your suppressor between hosts, a quality muzzle device is the foundation of a reliable, repeatable setup.

The 3-lug design is SilencerCo's answer to shooters who want something faster than direct-thread but more secure than improvised solutions. Threading it on is straightforward, and once mounted, it gives you a solid mechanical interface that won't loosen or rattle under fire. The black finish matches most modern pistol builds and holds up to the wear of regular suppressor attachment and removal.

One critical point: this muzzle device is caliber-specific. The AC2605 is engineered for 45 ACP and will only work with SilencerCo's 45 ACP 3-lug suppressor mount. It is not compatible with 9mm 3-lug mounts or any other caliber's attachment system. If you're running multiple calibers or suppressors, verify you're pairing the right can to the right device.
