Hey Mosin, If you are going to do the scout type setup, I have the B-square mount that replaces the rear sight. Yours for the cost of shipping. If not, I would not go with 3-9 as I did, but probably 2-7 like I am planning. I had to use High ring in order to use a 40mm obj scope. It is just too high for me. I don't plan on using it over 300 yards anyway, so I do not need quite that much magnification. I would use a quality optic though. That ol 8mm can beat them up.
I got all the cosmo out of my stock by using brakekleen. Spray it on, soak for a minute wipe it off. Repeat, repeat, repeat. It does suck out that oil though. You will have to get it out if you want to bed the rifle, or that cosmo will make the bedding release. I chose rosewood colored stain. I like it anyway.....
Here is a pic or two of mine, still under construction.......
