[Any advantage to using the sight for the AE over one set up for side mount drilled and tapped?? ]
If your Model 92 is already D/T'd on the side, i.e. set up, it would make more sense to use the side mount peep in the existing holes, ILO D/T'ing two more holes in the top rails.
If your Model 92 will have to be D/T'd somewhere, depending on what peep you choose, IMO I don't think it'll make a whole lot of difference.
I had acquired the 94AE peep in a sights trade - so used it because I had it on hand - and posted the results so others could see it would work.
The side-mount peep should clear the issue bolt safety, if it's mounted in the proper position - just ahead of the thinner locking lug mortices. There, the horizontal peep bar will cross the bolt ahead of the lug area, well forward of the safety ears with the bolt closed.
The top-mount AE peep is also mounted just ahead of the locking lug mortices, but it's design carries the horizontal peep bar behind it's base, over the rear half of the locking lugs - where it might be contacted by one of the issue bolt safety ears when the bolt is all the way forward - unless the underside of the bar is relieved to clear the safety ear, or the safety given the vasectomy.
I'm currently working on yet another low-mounted peep - just a Skinner Lo-Pro mounted in the center of the vasectomized bolt safety body..............................
