There is a reason the HK 3-lug system has stuck around for decades: it just works. The SilencerCo 3-Lug Muzzle Device (AC2609) brings that proven quick-detach setup to any 9mm barrel with 5/8×24 threads. Spin it on, torque it down, and from that point forward your suppressor attaches with a quick push and twist instead of threading it on every range trip. It is a small part that makes a big difference if you swap your can between hosts or just like getting set up fast.
SilencerCo machined this adapter around industry-standard 3-lug dimensions, so it plays nice with 3-lug mounts built to typical specs, including both the original SilencerCo 3-Lug Mount and the newer Low Profile 3-Lug Mount. Through that mount, it supports popular SilencerCo suppressors like the Octane series, Omega K series, Hybrid 46, Hybrid 46M, and Omega 36M (the Hybrid and 36M models need the appropriate Bravo or Charlie piston mount). One thing worth knowing before you order: 9mm 3-lug muzzle devices only pair with 9mm 3-lug mounts, so match your calibers accordingly.
The 5/8×24 version measures 2.3 inches overall and adds about 1.9 inches to the end of your barrel, which is worth factoring in if your build is tight on length. Machined wrench flats mean you can snug it down with a standard wrench, no exotic tools or guesswork required. The solid steel construction wears a matte black finish that blends in with just about any pistol caliber carbine or subgun-style build.
If your suppressor lives on more than one gun, quick-detach mounting saves real time and hassle. The 3-lug interface locks up tight and repeatable, and it is a natural fit for fixed-barrel 9mm hosts like PCCs and large-format pistols. Thread one of these on each host and moving your can between them takes seconds instead of minutes.
No, this is just the barrel-side adapter. You will also need a 3-lug mount for your suppressor, sold separately, such as the SilencerCo 3-Lug Mount or the Low Profile 3-Lug Mount. Once you have both pieces, the suppressor attaches and detaches in seconds.
Paired with the appropriate 3-lug mount, it works with the Octane series, Omega K series, Hybrid 46, Hybrid 46M, and Omega 36M. Keep in mind the Hybrid 46 needs a Bravo piston mount, while the Hybrid 46M and Omega 36M require a Charlie piston mount. It also plays well with other brands' 3-lug mounts built to standard HK dimensions.
No. SilencerCo's 9mm 3-lug muzzle devices only interface with 9mm 3-lug mounts, and the .45 versions only work with .45 mounts. Make sure both pieces of your setup match in caliber before ordering.
The 5/8×24 version is 2.3 inches long overall and adds about 1.9 inches past the muzzle once installed. It also has built-in wrench flats, so installation is as simple as threading it on and snugging it down with a standard wrench.
