If you want to scope one, I have used the scout scope setup. The mount replaced the rear sight and scope has up to 10" of eye relief, also no need to bend or install bent bolt. I liked it better as with this set-up the scope sight picture is quick to aquire and there is no chance of getting 'scoped' during recoil.
I installed a ATI monte carlo stock, scope and mount for $115 shipped thru ebay, on a M38. It was a blast. And can be returned to factory stock without modifications) ( had bit of an issue with the mount being sloppy, but could have been fixed with shims, but I sold the gun back to original owner,the part are to go onto the 91/30, but look to be 'illegal' for the Vintage shoot, ;( )
