An AK-47 is not a good sniper weapon. Supposedly we have radar systems that can trace bullets back to withing centimeters of their origin.
Yup. We have artillery that can shoot 11 miles and come within 2 feet of the target. Amazing.
Not radar. Accoustic. Basically an array of mircrophones that allow you to direction find the shot, with multiple lines of bearing from different pairs of michrophones giving you the location. Problem is that they don't work very well in an urban environment, due to multiple reflections from large buildings. They work better than one might think, but still not all that well.
AK47 is an assault rifle, firing an intermediate power catridge. The AK series are not known for their high accuracy. Even the Soviet design sniper rifle, in 7.62X54R (a catridge dating to czarist times) is not nearly as accurate as what US, UK and other western forces use. Accurate enough in most military situtations though.
An AK-47 derived RPK squad automatic weapon with the longer 24-inch barrel is. So is the heavier caliber AK-variant SVD sniper's rifle designed by Yevgeniy Feodorovich Dragunov.
Either might be described as *an AK* either by unknowledgable news reporters who can't tell an AKM from an M16A2, or to a lesseer degree by a grunt infantryman who cares primarily that it's something that goes bang and is pointed in his general direction.
