Where is the scoipe supposed to be mounted on a M1903a4?

Original photos taken during development of A4s with the M73 (Lyman Alaskan) scope which was the original intended scope, has the adjustments ahead of the front ring. Proof of this is also why the tail end of all GI bases had to be stepped and beveled to accommodate the ocular bell and lock ring. That being said, some shooters physical build simply do not work well with that setup. I for one find this forward setting almost impossible to use with various positions and maintaining shot consistency, even in prone. You also might not be able to forward mount your anyway, looks like the base will not allow it without some machining or taller rings.

On another note in regards to another comment, the Weaver 330/m73B1 started as a temporary substitute due to Bausch and Lomb's inability to provide glass for Lyman. So... an M73, M81 or m82 is in no way incorrect for the A4. By the end of WWII they were being installed on A4s in replacement situations.

Just curious about the second photo, are you able to operate the bolt on that rifle with the eye cup on the scope? With my setup (yes , I know they weren't intended for use on the A4) there is not enough clearance for the bolt handle to pass with the eye cup on.
