being a production gun, id think that if you bought a flintlock and barrel for the stock, it aughta drop right in...almost willing to bet the stocks are cut the same...

but, your looking at a few hundred dollars...may as well pick up a used flintlock IMO...i almost tried it because id like to have a percussion gun to hunt with in rifle season when its wet out...

never thought the barrels and touch holes wouldnt line up...but i guess they may not..and with a flintlock its gotta be right..
