The new auto PAM, both by DSN and Josh/Andrew etc, have a recessed cyclops embedded in a sandwich crystal, like the gen.
This prevents from the ability to replace the cyclops.
The only way to have it perfect would be that the manufacturers design a perfect cyclops, like OP did. So far they designed and made an almost-perfect, still not perfect, cyclops.
Also, there is a chance that OP used aspheric cyclops in order to lessen cushion distortion that arise from great mag power. In this case, the cyclops alone would cost about as much as the whole rep.
There is nothing that applies to any PAM with a cyclops, as some PAMs have the abovesaid recessed cyclops, other don't, some have an additional small lens embedded in the date window, other don't, etc...
