She introduces herself as Bushmaster ACR, except she fires in full auto, meaning she's actually a Remington ACR. This is kind of annoying. They should have just let her use her original name of Magpul Masada, seriously. It sounds cooler.

That aside, she has the potential to be stronger than AR-15! ...If you don't mind crippling the rest of your echelon's DPS to do so (Dusk has math figures in the expanded section).

She's honestly not bad, with 65% DPS up baseline and can get free damage stuff in if you have debuff effects already going, but she's not critical or anything. Basically suffers from "there's lots of super good ARs and she's not super good enough to displace the ones you already have."

Basically M1 Garand hit by a Japanizing beam courtesy of the IJN (which is why she has a sailor uniform). ...And then it changed her skill to something actually vaguely useful.

Every 3rd shot she fires is a line AoE that doesnt miss, but sadly cant crit. This is actually pretty cool at night vs evasive enemies, like Uhlan formations in a post CT-environment (Uhlan formations start having evade), though actually a bit of a DPS loss on nonevasive enemies.

Not exactly a normal use rifle, but the niche she has comes up fairly often so having 1 on hand is useful.

A doll that was forgotten for so long I couldn't find a cleaned up version of her image outside of moegirl.

Her skill does different things depending on whether its a day or night battle. Crit and Damage during the day, Hit and RoF at night.

She's not actually bad, just that she's not exactly overwhelming good, so she just... kinda exists?

And then Shattered Connexion happened and she was helpful against a certain enemy type, but that's far in the future. For now, eh... raise or don't raise, whatever, you'll be fine either way.
