So, I'm looking into getting my hands on a short barreled shotgun with a pistol grip rather of a shoulder stock, but I'm a little iffy on exact NFA rules. I understand that what I want will be classified as an Any Other Weapon, due to it not being made to fire from the shoulder, rather than a short barreled shotgun, which are. AOW only require a $5 tax stamp, versus the $200 for other class 2 firearms. However, want about the tax stamp for making such a weapon? If I were to buy say, a stoeger coach shotgun, what exact process would I need to go through to legally be able to cut down the barrel and either switch out the stock for a pistol grip or cut that down as well? Would it be easier/cheaper to just find a smith in the area to do the work for me? also, if it would be easier to just have it made for me, I live in the portland metro area and don't drive(never need too out here), anyone have any recommendations for where to get the work done at?
