Well, I just try with the electrical soldering pistol and all the screws are in the same place (they refuse to move!)
I aply the heat over the screw head with the soldering pistol for a couple of minutes; the metal around turns warm and the brillant glue now is dull, but the screws do not move.
What do you think: apply the soldering pistol for more time?
I am afriad to damage the components inside the scope (a Swarosky).

I still need your advise.

Best,

Jose M. Fernandez
