0.36g GoldenBall BIO 1000 BBs (Black color).
A relatively new arrival to the airsoft arena, GoldenBall BBs are produced out of China. These new comers are of surprisingly good quality for the price. Each BB has an high polish, high tolerance finish making them perfect for use in all upgraded AEGs, upgraded spring guns, and high end gas guns. However the heavier weight of this BB makes it ideal for sniper rifle use.
