The Coast to Coast Master-Mag model 880 is a 'House brand' Mossberg 500. I haven't found out much else about them so far, there isn't a lot of information about them on the net unfortunately. * update* Found out they were made from the late 70's to early 80's, no exact dates though. Could this have been made by Mossberg? We have a Master-Mag 880 and would like to find out too. I just bought my son a Coast to Coast model 880 shot gun w/ a bird barrel and a slug barrel. We are also trying to identify the manufacture, but interestingly enough, my Mossberg 500 slug barrel is an identical fit! This one is has "50 Years" embosed on one side. We paid $100.00 for it this afternoon, which I cansider to be a good deal!
Possibly. The rounds should fit into the mag. The feed is more based on the trigger group than the mag (mag has almost no feed lips).
About 250 without scope.
Mossberg.
100-400 USD
