SilencerCo AC2607 3-Lug Muzzle Device 9mm Luger 1/2x36 Steel

The SilencerCo AC2607 3-Lug Muzzle Device is a purpose-built silencer adapter that threads onto the muzzle of a host firearm to provide a quick-attach 3-lug mounting interface for compatible suppressors. Machined from durable steel and finished in a clean Black finish, this muzzle device is purpose-designed for 9mm Luger firearms and matches SilencerCo's suppressor lineup.

The AC2607 installs on barrels threaded 1/2x36, allowing the shooter to mount any suppressor equipped with a 3-lug coupling. The 3-lug system provides a secure, fast, and repeatable attachment point - ideal for pistol-caliber carbines, PCCs, and fixed-barrel pistol hosts running 9mm Luger where rapid suppressor swaps are a priority.

SilencerCo engineered the AC2607 for shooters who want a rugged, dedicated mounting solution for their 3-lug suppressor. The steel construction ensures long service life under repeated attachment cycles and high-volume fire, while the precise thread fit keeps the unit concentric and aligned on the host barrel for repeatable point-of-aim and point-of-impact. Whether you are building a dedicated suppressed 9mm pistol-caliber carbine or simply want a clean, secure attachment point for your 3-lug suppressor, the AC2607 delivers the reliable performance SilencerCo is known for.
