A word about the magazine that comes with the upper. These magazines will not accommodate all 2 1/2″ 410 gauge shells. 410 ammo varies in length by manufacturer. If the shell will go in the magazine with out forcing it the magazine will feed fine. This is the main issue people run into when shooting their uppers.

    All I get is a single shot. 2.5″ shells are still to long. They hang in the magazine. I would stay away until someone can develop a shell that’s at least a 1/16 inch shorter. I even shaved the shell, but you got know when to stop otherwise all your shot falls out. I’m not happy.

      I am sorry you are having trouble finding 410 ammo that is the correct length. This issue is addressed on the product page. We have a list of ammunition we know that functions very well in these uppers. There are more types of ammo that work than those that don’t. Another alternative is to use the ATI magazine. They have a patented cut out in their magazine that let’s it accommodate pretty much every 2 1/2″ 410 shell out there. Please call me with the brand of ammo you are using and let’s try to see what is going on.
