I use the M16 only since Black Ops, and MW3. I hated burst weapons in MW2 lol but that's way back when I first started CoD. The M16 was good in Black Ops no recoil, and could pick people off easily from a long distance. I kind of miss Hardened perk from that game because I think it really made it more efficent.
The M16 is a joke in this game. It has more recoil than the ACR (it's a burst weapon, why does it even have huge recoil?) It needs buff, but I know it won't get any...and if it does, well call me surprised. They need to lower the recoil by a good margin, and swap the damage with the Type-95. Why is the Type-95 a faster burst weapon AND deals more damage? How did they figure that was going to balance the burst weapons? So what the M16 takes 1 whole less burst to kill at long range, the spawns make it impossible for that to happen anyways. I also think the M16 is the worst gun in this game...
