These Valken Field 0.20g plastic airsoft BBs are the perfect airsoft starter pack for rental guns, or new airsoft players. These 6mm BBs from Taiwan are highly polished and seamless giving you greater accuracy and consistency, and they are packaged in a resealable bag making storage, transport, and loading simple and convenient. We recommend using our Valken airsoft BB Speed Loaders for use with Field BBs when loading mid-cap magazines.
