I bought the wolfie for 3 months, 15 days left T.T, it is incredible, the only downsides is that its slightly inaccurate and is slow to fire the next shot. But what people don't understand is that its still a sniper rifle, a weapon designed to be deadly as it is accurate. The margin of error between each shot is barely noticeable. If you master quick scope, drag scope, and no scope, you will be unstoppable.
Pros: 1 shot kill, accurate, can be used in medium and long ranged combat
Cons: Slow to fire next round, If you want accuracy over fire power a sniper rifle like the m24 would be recommended.
The m24, is however the most accurate rifle in the game, even the a1 will be a 1 shot kill to chest back and pelvis is they wear light vest. However, since its is bolt action it mis even slower the the l96 to fire the next round. I have yet to try the a3 and don't have anything say about it.
Pros: Accurate...as hell
Cons: Slow to fire next round, low damage for a sniper rifle. Only recommended for long range fire.
