Description
The SilencerCo 3-Lug Muzzle Device (AC2607) is a factory direct quick-attach suppressor adapter for 9mm pistols and pistol-caliber carbines with 1/2×36 threaded barrels, built to pair with the SilencerCo proprietary 9mm 3-Lug Mount. This HK-pattern 9mm suppressor muzzle adapter gives fixed-barrel host gun owners one of the fastest and most secure suppressor attachment systems available for pistol-caliber platforms.

Special Features
The 3-lug design follows the HK-pattern quick-attach standard, allowing the suppressor to lock on and release with a simple quarter-turn rotation, removing the thread timing and cross-threading risks that come with standard threaded mounts.
SilencerCo specifies that 9mm 3-lug muzzle devices must be used exclusively with the 9mm 3-Lug Mount, maintaining proper bore alignment and locking interface integrity across the full system.
This muzzle device is engineered for fixed-barrel host guns including pistol-caliber carbines and semi-automatic pistol platforms where a direct-thread or piston-style suppressor mount is not a practical option.
The 1/2×36 thread pitch serves a specific range of 9mm platforms, particularly certain pistol-caliber carbines and host pistols built to this thread specification, making the AC2607 the correct factory-fit choice for those barrels.
The steel construction holds up to repeated attachment and detachment cycles without wearing the lug interfaces, maintaining a solid lockup over extended service life.
Practical Benefits
The quarter-turn 3-lug attachment means you can mount or remove your suppressor at the range or in the field in a single motion with no tools, no timing marks, and no thread engagement required.
If you already run a SilencerCo Octane or Omega K Series suppressor on another host, the AC2607 brings that same can to your 1/2×36 threaded 9mm platform without purchasing an additional silencer.
Fixed-barrel 9mm carbine and pistol owners who cannot run a standard piston mount now have a purpose-built adapter that integrates cleanly and securely into the SilencerCo suppressor ecosystem.
The compatibility across multiple SilencerCo suppressor families means one muzzle device investment supports a broad range of current and future suppressor options as your setup grows.
If you are equipping a 1/2×36 threaded 9mm host for suppressor use, the SilencerCo 3-Lug Muzzle Device (AC2607) gives your fixed-barrel platform a confidence-building foundation for fast, repeatable suppressor attachment.
The SilencerCo 3-Lug Muzzle Device (AC2607) in 9mm is a practical choice for the pistol-caliber shooter who wants the speed and security of HK-pattern quick-attach suppressor mounting on a 1/2×36 threaded host gun.
