The SilencerCo 3-Lug Muzzle Device 9mm 1/2×28 is the barrel-side half of the SilencerCo 3-lug quick-attach system for guns with fixed barrels (brand part no. AC2604). The system needs a 3-lug mount to attach a suppressor, and that mount is sold separately. This is the 9mm version with 1/2×28 threads, and the 9mm devices must only be used with 9mm 3-lug mounts. It is made by SilencerCo, which offers the 9mm device in several other common thread pitches.
