reliable due to being manufactured loose so they can take more abuse as compared to the black rifles tight tolerances. The Dragunov is a AK based sniper rifle and they one of the deadliest known to man if placed in the right hands. The AK is also a very deadly accurate weapon even in longer distances compared to the black rifle ( due to the AK firing the 7.62 rounds compared to the ARs 5.56) and its also a gas piston setup making it more " accurate", the AR/M16 uses a direct impengement system. Basically the AK seems more in- accurate than the AR due to kick were as the AR is lighter and less kick more likely to dirty up and jam. http://en.wikipedia.org/wiki/AK-47 http://en.wikipedia.org/wiki/AR-15
