Weapon Poll

Hai.

I got a poll for all of you, that could not only help me, but everyone who needs that same response. Are you ready? I'd like the opinion of everyone, and also a "why" would be great. So here is the question:
*Between AK-47, M4A1 & Scar Light, which gun is the best for someone with a great aim?*

Thanks for replying, much appreciated.
