M14 is my most used weapon and my KDR just keeps climbing so worst weapon no way . I does take some skill to use but it's a very good weapon. I just equip it with the grip and nothing else as I run scav pro and it usually kills with 2-3 shots . One funny thing is I tried using it with Hardened pro the other night and did worse with that perk than I do with SOH pro. I tried it for several games to make sure it was not just an off game but every game was worse than normal .
