No, BAR doesn't have BAR rounds. BAR uses .308 Winchester rounds, as well as M1 Carbine. Other guns such as M4 use 5.56x45mm as well as Famas, G36, HK416 and multiple other weapons. Others use 9mm such as UZI or MP5. Others use .45 ACP such as M1911, Vector or Thompson. Others use 7.62x39mm such as AK47, AKM. Each ammo should cost the same and according to the time it lasts - like $200 for 2 days, $700 for a week or $3000 for a month. VIP should still have unlimited ammo for all kinds of ammo.
