0.20g Excel 3700 BBs
These high quality BBs are manufactured by Excel in Japan. Excel produces these BBs under the Standard Formula label, which means that they are not biodegradable. Excel is one of the oldest companies to produce BBs for the airsoft market and are considered the original, high quality, standardized production BB. Produced with a very high polish, they are recommended for all AEGs, gas-guns, and spring guns. The exacting standards involved in production make these perfect for use in high tolerance tightbore barrels.
