Sorry, this isn't a handgun question...but I'm sure someone in this forum will be able to help. I just bought the Mossberg 500 Tactical Cruiser with the breacher barrel. I want to dress it up this "ZOMBIE KILLER", but I can't seem to find a heat shield that fits. Due to the breacher tip, all other heat shields' bolts hit the choke/barrel brace. Can anyone help? It has a pistol grip...it's like a really big scarry pistol, I guess.lol Thanks for your help.
