I don't think you should have to pay return shipping. It's not your fault! I hear from lots of people that Mossberg has bad customer service and it takes them a long time to get back with people
Better polish up on your reading comprehension. He said they sent him a shipping label. And you can tell "lots of people" that they don't know what they are talking about. Mossberg and Remington have the best customer service in the business.
