Looks good Rob! I highly recommend Tech Sights if you want to go with a rear peep sight.

I went with the AK200S for my Maadi (will also fit your Hungarian) because it's both windage and elevation adjustable. The AK100S is windage adjustable only, so for elevation you'd have to raise/lower your front sight post.
