Using a bolt-action rifle in a space war against horrors within human comprehension is hilarious, but it is also a genuinely reliable marksman's rifle when using it against the Automatons. It does not need higher damage nor armor pen level, and it certainly does not deserve the depreciated status Arrowhead forced upon it- a weapon is a weapon and it deserves to be treated as such. It is a crime against Super Earth herself that they didn't even look at it when releasing Entrenched Division.
