Haha, I like that....
Obviously, the charging handle on weapons such as the AK serve as the "forward assist", that the AR has. An aspect that is often over-looked concerning the reliabilty of the AK is that its bolt/carrier/piston group is heavy... thus, it has so much more energy coming forward compared to the AR (which relies on a strong recoil spring). This heavy operating assembly is what gives the AK near unsurpassed reliability in the battery going home arena. Another design aspect of the two bolts is the manner of which they "lock up". The AK doesn't have any lugs to lock into, only a rotating bolt. This enables there to be less opportunity for gunk build up in fine spaces, like the precision AR. The locking lugs of the AR, IMO, aren't an advantage for a combat rifle. In an effort to maximize reliability and mass production... the AK suffers in the accuracy department. However, I submit here... the majority of fire fights happen within 300m, within the effective range and accuracy of both the AK and AR(M4). "The enemy of best is good enough", the AK is simply that... good enough. No more and no less, it does exactly what it was designed to do. The AK is a tool meant to be abused by illiterates, peasants and suffer abuse like no other. Mission accomplished.
