Between her two modes AND a passive that helps keep shotguns alive, I don't think there's much more to say other than "she's great, you will probably find a use for her."

Like every other DPS shotgun, she really doesn’t have a place in current content. A phrase commonly used around here is “a solution in search for a problem”, but the real problem with MAG-7 is that I’m not entirely sure she’s a solution either.

Her passive effect can be very nice when enemies start having 600 armor, but the times there are less than three targets are very rare. Her active skill can make her damage go sky high if it’s allowed to stack, but her being on the frontline gives her the same issues a lot of DPS SMGs have. She’ll lose links, cutting her damage by a ton. Not to mention that it takes a little while for it to ramp up. The DR afforded to her by the skill isn’t high enough to keep her healthy enough to do much.

The Steyr ACR is the gun the Pallet Rifles in EVA are based off of, and this one is about as useful. On one hand, it seems like she'd be good for para fairy and its debuffs (you get +25% final damage with that), except it isn't enough to make up for the debuffs still. It's also not very easy to get debuffed. Evaluation may change based on future enemies, but really it's not worth it when you have so many good ARs to choose from.

Can she dethrone AS Val's ridiculously solidified position as a top-tier damage dealer? ...Not really. She suffers from wanting some base crit rate, but making use of her crit rate requires either targets with shit evasion to begin with, a ridiculously high hit rate modifier somehow, or some other means of hitting targets at night. She might have some uses, but she's harder to use than AS Val, and you don't get much in exchange for it.

Her Mod 3 unique equip is alright. It lets her punch through lighter armors, and otherwise is excellent at finishing off weakened enemies, rather than wasting full-power shots on them. This is usually a thing with rifles that don't quite instantly giblet their foes. Her tile buffs are pretty okay.

She's alright but not a priority.
