I wouldn't be surprised if somewhere along the lines German scope makers (and with their healthy obsession with precision which is actually a good thing) may want to create a scope that extends a Cyclops' already impressive sight like making it reach an absurd level of 6km.

Actually they'd go the other way. They'd reduce the size and power of the scope to make for better handling. There is no point in making a powerful scope if there isn't a gun that can take advantage of it.
