The scope on the Mauser, has a telescoping rubber attachment on it's Ocular lens.
The scope could only be moved forward by about 1/2" by the looks of the front dovetail.
On a 10.75x68, I would not want to shoot that rifle.
With the drop to the heel, appearing to be sighted for irons, with such a high mounted scope, the end of your chin would be the only cheek weld.
There would be quite some head movement with recoil. No, I would not want to shoot that rifle equipped as it is.
I do like the heads-up attitude this rifle requires when shooting with a scope, just that the scope is too far back as well as having that rubber eye-piece that would impact around the eye upon recoil. NOPE! WOULD NOT SHOOT IT AS IT IS.
