If you get selective fire and extended mag (use fast mag til you get there) you'll def take people down fast. If you camp where I was staked out on Slums in that SMR video near the end, you'll pick up kills fast with the FAL... people camp in that room all the time, its a sure thing you get some head shots. If anything they will run out toward you like they were in the vid. Just make sure you have a bouncing betty on the other side of the van to give you some warning in the case that someone is trying to get to you from the other side. Another good place to do this is on Hijacked, on the spawn side with the life boats, If you get between the wall and the boat on the left, and keep ADS down at the door way, you'll pop a few kills before they try to come for you... again, a bouncing betty placed behind you will help greatly. Carrier is the best map for the FAL, you can always head shot snipers up on that ramped platform, or standing on the jets. Knowing what guy you're being killed with is a bit difficult in this game if you aren't use to COD. Thats one thing the MW line does a bit better. Generally, in the kill cam it will tell you what gun it is plus all attachments they are using on it. I don't think it does in this game, but I don't spend too much time on kill cams anymore.
