Every bit as good as she used to be awful; this is quite a feat, since she used to be IMMENSELY awful. You can make a fairly convincing argument she's a better value mod than AR team these days. She's that good. She's a little hard to use, sure, but she has piercing on a rifle and all sorts of minor extras.

She does have the issue of "can't equip PEQs" and thus suffers as much as any other rifle at night, but a rifle capable of dealing with enemy clusters a la M4 is very nice to have in general. She gets very heavy use in rankings for a reason.

Ironically for a rifle with a night-oriented skill, she works best during the day, because yeah, that issue about not being able to use PEQs.
