This game has so many good ARs that if you somehow stumble into her, since she's drop only, why would you ever use her? Even in a 3* only challenge account, why?

Trash, just as all other 2* ARs. Don't bother going for her Mod3, it's still terrible, effectively giving you what amounts to a slightly better HK416, but with a lot more effort involved.

If you REALLY want to have more info about her mod 3, look at her mod article.

The Right Arm of the Free World

There was a time she was good. That time was before we got grenadiers that shot as fast as she does. She does fire three grenades though, although they are weaker than everyone else's. Has the odd use here and there, but time and powercreep have not been kind to her.

Has daddy issues with M16 and the grump of Squad 404. She says she's the only one you need. What she doesn't say you need to mod her to do so because she's garbage before the mod.

Her mod article can be found here

Kind of fetishized and sort of jailbait, but she's still a very solid option if you have her special equipment. Outside of that, she's pretty mid. She used to be the standard ARs were judged by, but now she's pretty irrelevant.

Kishiyo face, and a silly source of drama, because he had a bitchfest over her VA not being someone super famous. As of GFL2, this continues to be true! She caused even more drama!

As a T-Doll? She's...not really that good anymore.

Civilian version of a gun even the Chinese Army realized was a bad idea. Used to have a niche use for battles that needed fast skills due to her low initial cooldown, excellent uptime, and unique equip, putting her in a good spot as a second-string AR. Unfortunately, there are now lots of good ARs, and the existence of chips has improved a lot of other ARs while she got left behind.

See the icon? Thats all.

Mod isn't worth it either, but has its own entry.

The Night Empress. Unfortunately, she's been going the way of many a monarch with the lower class overthrowing her. She used to be the last word for night battle ARs, but with AS VAL's mod, she has fallen behind. Turns out, being able to use a crit scope at night is very good. That being said, +200% damage at night is still decent and if you can't afford the mod, she's a good replacement.

Also, while enemy armor stacks superhard now, it's actually fine if you have sufficient +FP on your ARs to punch through. If you don't though, this still wont save you.

The most German unit in the game, in that she is both exceptionally lazy and surprisingly good at her job whenever she can be bothered. The source of 90% of HK416's misfortune. Zombie movie afficionado, and owns all 26 seasons of The Flying Dead (Im not making this up.) Originally one of the most broken ARs in the game until digimind evolution and team DEFY showed up. First member of Club "MGs who pretend to be ARs." Max out her skill, point and laugh as she destroys everything. Skill has poor uptime which makes her worse than AN94 in 90% of situations (and arguably worse than STAR Mod3), but still pretty good.

Her skill is completely useless against armoured enemies, which will become an issue later, when more and more armoured enemies appear.

And then her mod comes and she is a fucking god because it solves basically everything.

She's a nonstandout grenadier, and those are basically all meh. Technically she's similar to FNC, except she only comes from events and heavy construction so by the time you get her you will have better ARs.

The famed Tactical Tuna. Will do as well as OTs-12 if you're extremely hard up on resources and need another AR immediately for whatever reason. You won't likely need it since you get the AR team early but if you absolutely must have something or it must be 2 star...

Similar to G41 in performance (actually slightly worse, but not significantly) and the artist just drawing their weird fetishes that land you in jail. She's basically a 5 star equivalent of Tavor sharing the primary weakness of taking 6s to startup instead of 4. The skill is good while active, but YMMV.

Honestly, the issue with any AR outside of the big mod ones, is that they just get gapped so hard unless they have a niche. ART556 does not. So you could use her, but....eh...?

Extra notes available.

A worse FAMAS, and a good argument for why collecting trophy rifles isn't worth the effort.
