i've heard the red dots are pretty good.
I have a PK-AS, which isnt a true red dot, but is made in Belarus, where many of these Russian optics are made. It's built like a tank. it's simple, and very sturdy.
as for the manual....yeah, mine's in Russian. which is fine for me, i can translate it. but if you ask around on AK forums, im sure people will tell you everything you need to know on how to use them.
