AFAIK sniper rifles deal an automatic death crit but no conventional weapons damage - which is why you'll always get pretty low damage dealt when using a sniper centric approach.
As for Soviet glass, while the optical quality was indeed generally bad, the PU series of scope was mechanically pretty sound. But still, exceedingly unlinkely that it would hold up to a PTRS...
I personally own a 91/30 PU and the optics is more of a reflex scope. Very low power at 3.5x,
And while yes durable. The mount for it would have to be extra strong, Drilling mounting holes into
the Receiver and putting a simple mount like the PU uses probably would not work.
But more importantly, The 3.5x zoom is a joke for a rifle with effective range like the PTRS.
The only thing that you would want PTRS for in a anti personnel role is the extreme max range
And you would need a very good piece of glass (Durable, Bright, And high zoom) and a very strong mount.
In war time Soviet Union.. i just kinda don't see it.
