Very nice, i was looking at something like this last night too.
on the FAL:
Stopping Power perk is not optimal for this gun as it
only helps with 1 hit kill headshots (if that's your thing, go for it).
I recommend another red perk. Also note that Red Dot sight on a FAL is
slightly off centered, and equiping a holographic sight changes the
minimum damage to 40 instead of 35. Also has a cool reload animation.
Upon close examination, if you use holographic sight on a FAL, Stopping
Power actually becomes quite beneficial seeing as it will 2 hit kill at
any range due to the 40 minimum damage change (1.4x 40 = 56, 2 hit kill).
