Imgur: The magic of the Internet

Bubba hacked up the fixed rear sight on this rifle in order to install a ghost ring sight, and then poorly drilled the mounting holes before stripping them out. The rifle is now unusable.

The 6.5 marked rear sight is out of stock everywhere, but I managed to find a 7.65 marked rear sight. Can anyone tell me whether there is a significant difference between the two parts? They look identical to me.

I'd also appreciate any tips on how to replace the part. It appears that the stock and FSB need to come off. How is the rear sight block removed?
