Typical TTK rating system based on time to kill at mid, close, and long range. Priority to Assault style gameplay (I.e. can be used effectively on the move) Bear or B36A4 is the best AR right now it can be built to handle close mid or long range well and if you use my Bear-Grillz build you will agree. Nvo is 2ed best despite falloff at longer ranges. M4a1 for close quarters. Versatility becomes adaptability, this is "the way of the warrior" to fight knowing without knowing.
