Re: mosin nagant-91-30 customizing questions
The sniper style scope and mount require drilling and tapping the hardened M-N receiver which is no easy task. I did mine and sweated bullets trying to avoid breaking the tap or the drill The holes had to be made in an area that I felt somewhat compromised the strength of the gun (near bolt recesses in the receiver). Another poster here broke the tap off in this endeavor and junked the receiver. I carefully lined up the mount to the receiver outside surfaces only to find that the scope was not lined up with bore centerline. I would never attempt to do the drill and tap thing again on a M-N. If I just had to have the "look" of the sniper version I would pay a M-N gunsmith to do the job (there is one!) but that would make the gun cost more than it was worth.
If you have to have a scope then just use the scout mount and scope. It's a whole lot easier and does no harm to the gun. Or try using the open sights. With practice you'd be amazed at how accurately any gun will shoot with these military sights. They are most certainly minute of deer or minute of a person out to 200 or 300 yrds, if you do your part.
