Not a practical project but would make a conversation pice that "may" be fun to shoot . I have thought about a cut down Mosin Nagant to pistol length cut the stock to a pistol grip and shorten ths barrel and move the front site back . I will look up the laws regarding this , I have talked to others and some think if the barrle is under the max length for a handgun and stock shortend to make the overall length handgun length befor reasembley it would be a leagle handgun . Any imput would be apreceated .
