I recently bought a Golden State Enfield "Jungle Carbine" made from a cut down No4 Mk II and it carries the micrometer rear sight. A fixed peep when flipped down and adjustable when up. The fixed peep is pretty much a ghost ring. Not that I expect great accuracy from the gun but doing a bit of fiddling I found that a peep rear (Williams, Lyman, Parker Hale) shank almost screws into the fixed and gives a finer sight picture with its smaller diameter hole.
I ran a 7/32X40 tap through the fixed peep (shank threading of above apertures) and it cuts deep enough to hold fine.
Some additional work may be done, such as threading the shank full to the peep so that it sits flat against the sight base and allows the bolt to pass when the micrometer is flipped up. The standard fixed and stamped micrometer can be similarly modified to include the peep on the adjustable slide.
The peep on the fixed can still be used as a ghost ring, threads aren't visible when sighting.
Just curious - anyone else done this? Seems an easy improvement over issue.
