Because its a burst weapon. Ever try a selector switch on any other rifles? It puts 3 bullets in one area with minimum recoil. I went 27-1 with it today(6 of those were from my stealth chopper). Although I play hardcore so that plays a big part for it also.
Video games make you smarter. If it wasn't for Monster Hunter i would have never noticed that 60 was divisible by 1,2,3,4,5,6,12 and 15.
even bursting with the swat in full auto sucks its recoil is absolutely ridiculously high you can switch between full auto and burst but id rather not use the select fire since it does so well in med to long range in burst mode
