I've owned 8 out of the top10 rifles and,with the exception of the AUG, I can see why they were chosen. Only reason the AUG was chosen was because it was the first bullpup to enter service. I personally do not like the bullpup configuration because mag changes are more difficult. I agree with the AK being #1 simply because it is overall the best single weapon ever built, simple, robust and fairly accurate. I personally prefer the AR's, due to better ergonomics, sights and accuracy. I have seen AK's that will go toe to toe with a standard AR in the accuracy dept, but I think that has a lot to do with the ammo used. The AK gets hammered because of accuracy and the AR because of reliability, both of which I think are relatively unfounded. If you change the sights alone on an AK then accuracy will improve greatly. As to the reliability issue, I've never had a single problem with my AR. Interestingly enough one of my AK's stopped running because of trash in the bolt face.
