For a general purpose battle rifle, the FAL is head and shoulders above any of the other "main battle rifles" out there -- ergonomic brilliance being the place where it just beats the everloving snot out of the M14 and G3 all day long. It's combat accurate, though definitely not a good starting point for building a DMR.
Add to that, for a T2K world, the ability for the user to adjust the gas system easily to allow for hotter or weaker, cleaner or filthier ammo from various sources and you've got the absolute winner.
