an ak is the same thing as a tachi scorpion
if you werent looking for speed i would have gone with the shipka or pbp shot gun. but all around gun is prob then the m4 its 55k. its 95k with attatchment i think. it does 8 damage which is all you could want. sten is okay i beat several "pros" (as they called them selves) with my ak vs 2 stens. it all really depends on what your are skilled with
