Very solid 3 star that is actually better than most of the 4 star RFs (SVD, G28 and occassionally T5000 can outperform her, but she'll handily trounce most of the rest.)

You get her for free and she's amazing, due to very fast base RoF for a rifle. Less good now as the better RFs come along, but will last into the higher chapters easily. Now has her mod available.
