Excellent write up and great pics Citadel, I think you sum it up nicely. I'm surprised your pics show the cowitness over the centerline, when I bring the dot down for cowitness the front sight is in the lower right corner of the optic FOV and actually partially obscured by the scope body.
And no matter how hard I tried I couldn't get really good pics looking at the dot through the tube, I have to hand it to you, you did a fantastic job there.
Only thing I'll add is that these optics work best with both eyes open, which makes the scope body indistinct as you mentioned. In particular I used to feel the older PK-A was much too tubular but have since realized that I was probably using it incorrectly and even the very stout Rakurz basically disappears when both eyes are open. Another quick thing is that I couldn't get the top cover off the SGL31 while mounted. On my SLR105 I could get the recoil spring pushed in but the top cover still wouldn't come off even though I tried to rotate to the right. There just doesn't seem to be enough space for the cover to clear the receiver under the scope body.
(and I weighed mine in at .91 pounds, actually lighter than my PK-A at .95)

You can see here a center view of the reticule over the front sight post. If I moved my head to line the leaf up the sight post you can sort of estimate how much will be blocked by the scope body down on the lower right corner of the optic. I really couldn't get any good pics with my camera, probably because its an SLR type and the center of the lense is kind of far from the bottom of the camera.
And on the 12 just for grins, though the PK01 sits so low the cheekpad prevents it from used which negates having the SVDS folder. Looks cool but not practical with this stock.
I'm glad you dug these up and got Eastwave moving on them. I agree they are a little pricey but I'm glad to have one and definately want to say thanks for putting in the leg work to get them rolling. :)
