I bought a used 30/30 for $50.00 which has a part broken on it. It is where the stock bolts to the receiver, at the top, just behind the hammer. I don't have the other part to put back. I have a MIG welder and a torch. Could I braze or weld a piece to the receiver and file it to fit, or should I let a gunsmith do this one? I've shot it and it seems to shoot fine, but there is not much holding the stock on. It was made about 1969-70 and is in good shape other than the strap broken. Am I in any danger shooting it in this condition?
