8mm 0.40g Marushin 500 BBs (Blue).
These BBs are manufactured by Marushin in Japan. These high quality, high polish airsoft BBs are recommended for use with all appropriate high end spring and gas guns. At 0.40g, these BBs are at the heavier end of the scale for the 8mm BBs that we carry. Airsoft players recommend this BB for use in the 8mm sniper rifles and shotguns. Because of the weight, this BB will produce a small sized pattern at medium distances when used in a grenade launcher.

*For use with 8mm guns and grenades ONLY!
