But you might be right in that the slider was thought to be the replaceable part, and expendable.
The main reason for the front sliding part is the lateral adjust for the reticle of older european rifle scope, the other adjusting was a screw in the rear upper part of mouts. So the skilled gunsmith could tap the sliding part temporary away and file these front upper parts hooks the way as Der Ami described. And when ready just install the sliding part back to itīs place.
