The Japanese Type 99 rifle (early)（BR2） has a bug in its holding action, making it appear as if the left hand is suspended. But there is no bug in the holding action of the Type 99 rifle (grenade)（BR3）, when can it be fixed? It’s a simple model replacement and action modification, but nobody cares about it after one year！
if this is a bug than you should report it.
