I've only recently finished shooting in my new rifle and tried it with the mod on last night for the first time (first time I've ever used a full bore mod). When shot the sound/flip is certainly reduced but there is a distinct "ting" heard. I thought at first the round was striking the mod but I can't see any strike marks. It's factory threaded.
Is this normal? There was only me shooting so no-one else to ask if they could hear the ting from the side. My only other moderator use is on a .22LR which certainly doesn't ting.
