If Raine's assault rifle is an updated AK, then it uses a 7.62x39 round. Chief's ar uses a 7.62x51. Why does this matter? Raine's ar has slightly better accuracy and much better range; on the other hand, Chiefs uses a slightly larger round moving at a slightly higher velocity. Again, all of this is dependent on the theory that Raine's ar is simply a built up AK47. With the battle rifle being present, I don't see this being a big problem for chief seeing that it can reach farther than either assault rifle and uses a larger round (9.5) than either the AK47 or the MA5C. Note: if I'm right, these are Halo 3 weapons. Technically, Chief should be using his Halo 4 equipment; for instance, the MA5C isn't used anymore, it's been replaced by the MA5D (which, by the way, is a far better assault rifle).
