Gentlemen: While this subject is up I wonder whether a satisfactory solder could be applied to a top rib whithout complete disassembly. I have a twenty gauge LC that has a loose top rib. The bottom rib is fine. The top is still attached at the muzzle and halfway to the breech, firmly attached at the breech and only a very small crack past midpoint towards the breech. There is a distinct very low twang when fired. The attachment points are at the blocks I am sure. This gun is very serviceable otherwise and positively a shooter. Is there a type of solder that would accomplish this and not stick out like a sore thumb. The blue is mostly faded but still the gun is pretty attractive and is excellant in the field. Sincerely Walt from Al.
