The minute you shot your DP the value went down into the used gun market. No longer NIB it is a used gun. Look at it this way if you were buying it would you discount the gun for a repair? Without doubt. Would you discount a gun for a factory replacement stock? Perhaps but far less than a repaired stock. All things being equal I'd rather replace the stock and keep the old one. The next owner can have it repaired if he wishes but don't spend more money on it yourself.
