The SilencerCo 3-Lug Muzzle Device in 9mm with 1/2×36 threads (brand part no. AC2607) is the barrel-side half of the 3-lug quick-attach system for guns with fixed barrels. The system requires a 3-lug mount to attach a suppressor to it, and that mount is available separately. SilencerCo sells the two parts separately. It is the 9mm version with a 1/2×36 thread. Pairing the right caliber of mount and device is the one rule to remember with this system.
