Free Shipping in the lower 48!  Just add to cart and free shipping is automatic for the upper.The upper now includes the 2 of the new ten round mags. These mags now accommodate almost all 2 1/2″ 410 shells including Winchester and others that previously wouldn’t fit. Because of this we do not have a recommended ammo list as most ammo now works!

Package includes 2- ten round magazines, flip up front  and rear sights, bolt carrier group and charging handle. These uppers are designed to run on Mil Spec lowers. People with custom lowers may have issues if the buffer tube and spring are different from standard Mil Spec tubes and springs.

    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.

    It is picky about length of shells used. Handloaders can work around br using 444 marlin cases.
    Using H110, large pistol primer(Win ) Win 410 shot cup. 3 Horn .375 round balls.
    Use a 7/16 nitro card under shot cup. Use an over shot card cut with a 44 mag case.
    Balls weigh 80 gr, velocity is 1200 fps.
    I have had zero jams or failure to feed.

    After talking to Darren and buying shells directly from him my AR410 works perfectly. Looking forward to doing more business with him. Soon

    So far so good!! I haven’t got to shoot it much. But I noticed that the Fiocchi and the Ati runs pretty good though it. I did my research though before buying this and read about the mags don’t like all shells. One thing I did do with the mags was took my dremel and pulled apart the mag and cleaned up and sharp or burred edges. Not much but seems like it made a difference. Did that to the mags that it came with. Also ordered 2 Ati mags when I ordered this upper. Did the same to those mags and all 4 mags seem to work really good after doing it. Hope maybe this might help someone. But I do like this upper and it runs pretty good I think. Would recomend it.

    Also for got to mention United Sporting Arms was very helpful before I purchased this upper. Had recommended which ammo and let me know all shells arent the same. Thanks for the help and I do recommend these guys!!

    I ordered this 410 upper a few months back, shipping was fast. I I was finally able to get to the range today and it worked great. I purchased the Mags and the ATI ammo from here also.

    United Sporting Arms was Great to work with. Any questions I had before and after my purchase were answered quickly.
