I just got my Mosin Nagant 91-30 and cleaned and assembled it. Has anyone had experience with these gus? I would like to mount a scope but don't want to mount it way up front and have a long eye relief scope. They sell kits with a mount and a turned down bolt but not sure how to switch it out. Or if someone knew where I could get a new bolt with a turned down handle that would be nice to keep the original bolt as one.
