Restoreing a Mauser Standard action with an Israeli 308 K98 barrel and beech stock?

[Chuckindenver]

soft solder flows at less the 300Dg, so your statement that they were installed with soft plumbers solder is bogus, if you dunk that rifle in a blue tank the rear sight base will float off, as hot salts blue runs at 290 to 300Dg.
so..again...high temp solder is needed too install a rear sight base correctly...my cost on real high temp is well over 200.00 for a roll of it, then you have to use high temp Silver paste, at 65.00 for small jar,..and enough to to attach a mauser rear sight base would cost about 100.00 not including the paste, and my labor to do so.
for the record..i am against using JB weld, or 3M panel bond..those were options he asked about..
