Sgt. Miller's thread got me to thinking about my Mosin Nagant 91/30. At some point when I have the funds I want to install a scope on it. I have found the right mount for it, but have a question about the bolt. I don't want to do anything to the bolt that is on it as it matches the rest of the rifle. My question is this. Are the bolts for the 91/30's interchangeable? I am assuming they are but want to be sure before I seek out another bolt. It may just make sense to get another rifle to do this to because they are so inexpensive still. Thoughts from the experts?
