So... I've wanted to get into three gun for a little while, but I don't have a shotgun that would be suitable. (Okay, it would work, but I'd run out of time on most stages!) I just got an email from DK Firearms that said they had "Panzer Arms" shotguns that look like ARs back in stock. Is this a good idea, or just a gimmick? If I showed up to a match with something like this, is it even going to work for how the matches usually work? I don't care if I get laughed at if it works, but I want something that works. Let's assume that the arm will fire reliably for now, then I'll go from there. What I'm looking for is... "Is a semi-auto 12 ga box magazine fed shotgun what I'm looking for?"
