Why ruin the history of a Finn capture 91/30 by making it into something it NEVER was.Nice looking rig. I was just looking at the same scope and mount and considering mounting it on a Finn capture 91/30. I am still on the fence if I want to do my Finn or just pick up a Russian 91/30. The Finn shoots fantastic and that is why I am leaning that way.
How does your scope look? Is it the one the reticule stays centered and does not move ?
Get yourself an exsniper from the recent refurbs, There are quite a few PE/PEM/PUs if you look for them. I find exPUs often for $125 or less. Good luck.
