BAR is fine how it is. Its not like we could change anything anyway. All the bipod did in dod classic was make mini-mgers out of support class.
Also, BAR and Stg are exactly the same aside from ammo capacity. I spend a LOT of time playing support, they behave the same and do the same amount of damage.
Shot to limb - 37.5 damage (shown as 38 if single hit, 75 if two)
Shot to chest - 50 damage
Shot to head - 125 damage
If that's wrong, I will literally eat a bug.
