SilencerCo 3-Lug Muzzle Device - 9MM, 1/2X28, Black Finish AC2604
Product Description
If you are tired of dealing with direct-thread suppressors backing off during firing or getting cross-threaded on your workbench, switching to a 3-lug system is the most reliable remedy. Standard direct-thread setups are prone to coming loose under heat and vibration, requiring constant re-tightening that slows down your range session. The SilencerCo 3-Lug Muzzle Device converts your standard threaded barrel into a rock-solid, MP5-style quick-attach interface that keeps your suppressor firmly locked into place round after round.
This premium adapter is precision-machined from high-strength steel and finished with a durable, matte black protective layer that shrugs off the extreme heat, pressure, and corrosive carbon blast of hard use. Cut precisely to a 1/2x28 thread pitch, it drops cleanly onto standard 9mm pistol-caliber carbines (PCCs), sub-guns, or threaded handgun barrels. The 3-lug design gives you a perfect balance between reduced muzzle climb and absolute speed, allowing you to attach or detach your silencer in seconds with a simple push-and-twist motion.
By eliminating the shifting tolerances common to direct-thread attachments, this low-profile adapter provides an incredibly secure and repeatable connection that preserves your firearm's natural point of impact. It is an essential component for any shooter looking to optimize their 9mm suppressors across multiple fixed-barrel hosts with speed and total tactical security.
Each individual factory retail package includes one genuine SilencerCo 9mm 3-Lug Muzzle Device (1/2x28 thread pitch) with a matte black finish.
*Armorer Bench Notes & Compatibility Guidance: The SilencerCo AC2604 (Part # AC2604) is engineered strictly for **9mm caliber firearms with fixed barrels** and must be paired with a matching 9mm 3-lug mount assembly on your silencer. It is fully compatible with the SilencerCo Octane Series and Omega K Series, as well as the Hybrid 46, Hybrid 46M, and Omega 36M (when equipped with their respective Bravo or Charlie piston mounts). **CRITICAL PISTOL WARNING:** This fixed muzzle device is designed for sub-guns and carbines; if you install it on a tilting-barrel handgun (like a standard Glock or Sig Sauer pistol), it will lock up your action and prevent the handgun from cycling unless a proper booster/nielsen device assembly is used. Clean the outer lug surfaces periodically to remove baked-on carbon and ensure smooth suppressor alignment.
