Cybergun x Colt BioVal Outdoor Precision 0.15g Airsoft BBs
(Quantity: 5000 rounds)

"They are exactly as described in the listing. They work pretty well in my springer shotgun, heavier then 0.12's but still have enough spread. They aren't always the most accurate BB but they usually get the job done well enough in close quarters, where a shotgun shines best imo. Also very affordable.
