Well like you had a problem with the valve on the air bottle you bought and you took it back to Sportsmans, I would contact AA and tell them about this as it could turn out worse, no matter what you try and once you start messing with it you will have no redress whatsoever, as you say it is new you should not have to be worrying about this.
