I'm probably going to be branded a heretic for saying this, but IME, Commie optics SUCK. And that's not without foundation; I've been through a few (POSP, Kobra EKP-1S and EKP-8, PK-A, PK-AS)! They just don't have the same degree of durability, clarity, dot brightness, battery life, versatility and ease of use that Western optics like the Aimpoint and EOThing do. Hell, even lower-cost red dots like the Burris XTS-135 or SPOT MkIII (the current optic of choice for my "fun guns") are far superior to the Kobra or PK-A.
Of the Commie optics mentioned above, I liked the PK-AS the best. Glass seemed fairly clear and I liked the glass-etched circle-dot reticle with the no-battery black option, but there is no way to mount it low and centered over the bore, which is where optics belong.
I currently run Ultimak scout mounts on my AKs and like them quite a bit. If you don't want to go that route, I'd consider getting a BP-02 and modifying it in the manner described in the link you provided. Or else wait for Mark LaRue to release his AK side mount, but that could be quite a ways off still. Of the Western dot sights, I prefer Aimpoints to EOTechs for serious work, but that's a whole other discussion...
Good luck!
