So you took it to Cabelas, eh?
I bought my Maxus used there and had a similar problem to what everyone is saying, would shoot a shell and fail to cycle one from the magazine for a second shot. Took it back to them because it's where I bought it and I had to help the guy at the gun counter get the fore end off..
Took it to a gun shop and the guy there was super nice, spend an hour disassembling and cleaning every inch of the gun, and handed me a lubricant product called G96 for it. I was running the gun too dry before but with the G96 I haven't had a single problem, cold, wet, muddy, target shells or duck shells. Owned Brownings my whole life and love the way to maxus functions and points but I can't get over how high maintenance it seems to be. I clean all my guns after every hunt, I just wish it wasn't a necessity for it to function..
