KAK PLAN B AK74 MZL DEV M24X1.5RH

The KAK PLAN B AK74 muzzle device is a tapered-and-threaded suppressor adapter built for AK-74 platforms running M24×1.5 right-hand threads. If you're building a suppressed AK and want a rock-solid lockup with your suppressor, this is a no-nonsense choice: the tapered design seats repeatably against Plan B suppressor hubs, and the threaded interface gives you a proper seal without guesswork. It's the kind of component that lets you trust your setup downrange.

KAK made this from 17-4 stainless steel, so it'll hold up to the punishment of repeated mount-and-unmount cycles and hard use. The bore accommodates both 5.56 and 7.62×39 ammunition, so it works across common AK carbine builds. At 3.5 ounces and 2.55 inches overall, it doesn't add needless weight or length to your platform. Installation is straightforward—a multi-wrench is included in the box—though KAK recommends Rocksett and 20–25 foot-pounds of torque to get it right.

One head's-up: some suppressor manufacturers tie warranty coverage to the use of their own muzzle devices or approved adapters. Before pairing this with a suppressor, confirm with the silencer maker that Plan B hubs are on their compatibility list. It's a simple check that saves frustration later.
