Please to be noticing the lack of scope too, but meh, it's the thought that counts. In her defence, she's probably a bit too small to actually hold it with the stock in place.
FN Fal and M249 look vaguely similar when I squint at their Wikipedia pics.
Exchanged "fn_fal" tag (as well as "rifle" and "sniper rifle") for "m249_saw" and "machine_gun" until and unless someone protests loudly enough to change it.
