Plan B suppressor mount compatibility starts with verification.

A Plan B compatible muzzle device creates the firearm-side interface. A compatible suppressor also needs the correct Plan B mount or a correctly fitted HUB suppressor adapter. “HUB compatible” describes a common 1.375–24 rear suppressor thread, but it does not guarantee that every complete combination is safe or dimensionally compatible.
