Just a bit of an update on this thread I started some time ago. Against some advice I went to a couple local gunsmith and found one that could thread shotgun Barrel. Only drawback was he was only set up to do Remington chokes which we talk through things really wouldn't be that big a deal. So I let him do this I had way more than enough wall thickness in the barrel and everything worked perfectly and cost me a hundred and fifty bucks.
