I tried the Birchwood Casey shell catcher in my Browning Maxus Sporting at the trap range, and did not like it at all. Not to mention it looks bad on a nice gun. The guy next to me had a rubber band on his gun, and it worked well. Just didn't look to good. Here is a better looking option to keep the person to your right from getting pelted from your semiauto shotgun. You do have to manually pull the spent case from your receiver, but it's really easy.  Made of 1/8th inch elastic bungee cord with crimp connector and heat shrink over connector to protect your receiver. Will work on all Semi-automatic shotguns.

  Includes 2 bands   I pride myself on fast shipping. Item will be shipped USPS First Class Mail with tracking info.  Feel free to contact me with questions  608 574 6290
