There are two types of flash hiders–the more common one is the type that’s effective at hiding the muzzle flash from the shooter’s view, while the other type is designed to reduce visible flash to bystanders. A suppressor can be mounted over either type of flash hider, but it will be most effective on a gun with a flash hider that’s designed to reduce visible flash to bystanders.
