Howdy ,so here is the rest of the story , I own a pawn shop and one of my employees took the gun in on pawn the person never came back so it was put up for sale , he sold the gun and the person he sold it to said it would only shoot once then jam , he gave him back his money and we sent it to a local gunsmith ! I wish I new it was a 22Mag before it went into the repair shop where the gunsmith didn't figure it out until after he butchered some of the mechanism , this is a tube feed rifle and the model number is stamped under the barrel near the feeder slot of the tube , and the markings for the caliber are stamped on top near the sites .
