My project gun is almost complete.One problem is the front sight ,The original was dovetailed and silver soldered. It is now cut bask to a carbine length and i have to reinstall the front sight . Beings that i will make the sight ,do i dovetail the barrel or contour the sight and silver solder it on.The barrel wall is thick enough to accept the dovetail without wreaking it .Need some advise on what way to go
