Requires a compatible 9mm 3-lug suppressor mount for suppressor attachment.

The SilencerCo AC2607 3-Lug Muzzle Device is a 1/2x36 threaded 9mm muzzle device for compatible fixed-barrel hosts. It threads onto the barrel and provides a 3-lug interface for quick suppressor attachment when used with the correct 9mm 3-lug mount.

SilencerCo describes the 3-lug system as a quick-attach mounting option for guns with fixed barrels. This type of mounting setup is commonly used on pistol-caliber carbines, subguns, and other compatible fixed-barrel 9mm hosts where fast suppressor attachment and removal are desired.

1/2x36 9mm 3-Lug Muzzle Device: The AC2607 model uses 1/2x36 barrel threads and is intended for compatible 9mm hosts. Always confirm your barrel thread pitch, bore clearance, and suppressor mounting system before ordering or installing.

9mm 3-Lug Mount Required: SilencerCo notes that 9mm 3-lug muzzle devices must only be used with 9mm 3-lug mounts. The muzzle device is only one side of the system; the suppressor must also have the compatible 3-lug mount installed.

Fixed-Barrel Host Use: 3-lug muzzle devices are intended for fixed-barrel host firearms. Do not use a 3-lug mount as a replacement for a booster/piston system on a tilting-barrel semi-automatic handgun unless the suppressor manufacturer specifically approves the configuration.

Important Fitment Note: Always confirm barrel thread pitch, caliber, bore clearance, suppressor compatibility, 3-lug mount compatibility, host firearm action type, shoulder geometry, torque requirements, and alignment before installation or live fire.
