Since, My rifle was returned from Mossberg repair. I have no Issue with misfires, probably Because new barrel (Headspace ?) Trigger works fine. Doest Go into safe every other Round. Scope rail is aligned Good , not 6 mil to left. But when I first fired this Rifle I would hear a high pitched Vibration sound, like Metal. Same thing yesterday at Range. Does this rifle have an Issue because metal Action is bolted to Metal stock. Should action be bedded To isolate metal to metal Contact ? Does anyone hear this Sound , with same rifle ?
