Your photos appear to show an RC receiver with a flat milled on the left side. I do not see any holes. It looks as if at one time the receiver was milled for a side mount scope. Perhaps there was at one time some intention for it to become a sniper but I see no evidence that it actually was a sniper. Maybe someone more knowledgeable in snipers than I can see something I don't see.Help, I can not understand that for a carbine such... Sniper or not?
I do not beleave the Optic were the problem , Optics were not a Problem at this time . So must be another reason they were not used for LSR Rifles .It is possible that were as all the ones I have seen were Russian captured ,its possible they needed Regular K98s more than Sniper Rifles for the Russian Front at this time periodIt certainly has the potential to be a sniper with the milled left receiver wall. That is a feature that is not present on any of my Mausers. I am guessing they either could not produce the optics or get a hold of them and the rifles were simply made into the regular infantry model.
