No clue as I don't know much about AK's yet what is your AR for sale and/or sale price? Then I will see what you can find on that .308 AK on the interwebs and see if it seems to be a good match for the price. And then no clue if you want a .308AK or not so there is that to factor in. Not knowing much on the AK's I would have to do a lot of research on it to see if it is worth it to see if it is an extreme AK. Just curious what others have to say. Quick search on the scope it is worth anywhere from $200-350. And anywhere from $800-1200ish for the rifle without scope and stuff. No clue on the add ons.
