Modified 12 gauge 870 with Magpul stock set, Volquartsen extractor, Burris SpeedBead (3moa dot), Meprolight night sights and an extended and ported choke (worked the best). I chuck it full of the Federal 1 3/4" "shorty" load that has 15 - #4 buck in it. And I can fit a whole bunch of them in the extended magazine!
