Almost all available sources suggest Orita fired around 600 rounds/min. I think it’s reasonable to adjust its current fire rate from 520 to 600 without by any means compromising its status as a solid BR II option.
At the moment, this squad/weapon is in a kinda weird spot. The weapon itself is borderline too good for BR 1, but the squad (a medic squad with only 4 members) equipped with an Orita are a pretty lackluster option in BR II, as of today.
Either way, 520 rpm is more of an old design choice of balance rather than accurate.
