0.25g Diamond Ring BIO 2000 BBs.
These BBs are produced by Diamond Ring out of Japan. Diamond Ring is one of the newer manufacturers of airsoft products on the market. After extensive feeding and bore tolerance tests, we have determined that these BBs are of very good quality and have a premium polished finish. These BBs are recommended for use in all types of upgraded airsoft guns, however they will work best in tightbore and other high tolerance barrels. Because of the heavier weight, these BBs will have better accuracy when compared to 0.20g BBs. These BBs are also biodegradable so be sure to reseal the bag after use to help protect the BBs. Decomposition begins when the BBs are exposed to any combination of sun, water, or soil.

*Do not expose BBs to moisture and then attempt to fire them, they may jam in the barrel!!
