Basically what you'd expect from something that's the standard of the Mexican Army. Frankly, at this point there's so many good ARs that another one would have to be REALLY good to get a real recommendation, and this one isn't going to win any medals, but she has good uptime and is cheap.

Comparable to the Browning Potato Digger. There must be something about early model machine guns. Her skill gives her an extra long belt that activates three seconds in, and unlike Potato Digger, who sacrifices accuracy and gains firepower, she instead sacrifices reload time while gaining accuracy. While the extra reload time is a pain, she does buff other dolls while reloading instead of being useless. The accuracy boost is nice, but not a game-changer. It may help vs. enemies with a moderate amount of evasion though, given typical MG accuracy is kind of mediocre.

Suffers from not only being an MG, but an inconsistent one due to her passive. Her stats are alright, but her passive skill is unreliable, not that it matters much since it only activates on reload. The active suffers from the problem of activating slowly enough that you'd expect MGs to have already killed most of what you'd want to stun anyway.

Props for accuracy. She spends the animoo's story just living in the dorms and only coming out for tests or really weird situations where they cant spare bodies, and she's basically the same in the game - she'll be in your dorms a whole lot. She also has three unique items that affect her passive but otherwise all do the exact same thing. She isn't completely useless, but there's not much reason to pick her over other MGs that don't have finnicky mechanics, because you frankly will not need that many MGs anymore.
