Unlike the other shotguns, she's focused on firepower instead, with her skill basically making her go DAKKADAKKADAKKA. You would want an Acc scope on her so she can actually hit anything. Sometimes used in 1SG/1HG/3MG formations to provide MAXIMUM FIREPOWER. Tiles are a little eh for that though. Armour is average.

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 high RoF Rifle with good stats. Probably the best one for general use. If you've noticed by now, high RoF rifles are kind of good. Actually caps RoF if paired with Calico, allowing you use other damage boosters instead. With the October 2018 patch, RoF cap is higher, and Calico alone is no longer enough.

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.

Actually good for the same reason WA-2000 and M14 are. Sheer RoF with decent damage. The only 4 star rifle worth using by default who does not require you to jump through hoops to even matter.

She's one of the dolls of all time. Yup.

AKA ST AR-15, aka Star-chan. High stats, two accessory slots, and Unique Ammo (that you need to farm for) that outperforms regular HV ammo and doesn't require forever to build up. While not considered as OP as she once was, she remains a good unit to raise; if you partially raise her, she basically hits close to RoF cap on her own.

Her mod (and her equipment set) brings her back up to a decent spot as an AR. You can see her mod here

"Are you THAT short on ARs or need cheap equipment that badly?"

You get much better ARs from story events, and there's only so much that you actually need. If you need a cheap AR and already have FNC though I guess she can be useful.

Her exclusive, while it does give her more strength, doesn't let her outperform many 4* ARs.

G43 is similar to M14 in night battles, but with a RoF skill instead of damage. Was quite usable as a starter night rifle, and better than nothing, but you should really try to get a better one.
