How are you doing? I'm MA3 Amberg I've been in for 2 years now and I watch the show every now and then. Any how I was out gloose hunting the other day with my double barrel shotgun which has two different chokes in it so I can each the goose both far and near with a good spread of bbs. I got to think of the same concept only with one barrel being a shotgun and the other a m16. I was hoping you might be able to point me in the right direction so it would be possible to get a working model of the gun. please email me back at caseyamberg88@yahoo.com with whatever information you might be able to give. Thank You MA3 Amberg
