ECOBB Line
For faster outdoor decomposition, some players and field owners are asking for bio BBs.  BB Bastards' ECOBB line of BBs provides faster BB decomposition in the presence of moisture and light.  ECOBB packaging is unique and ensures that partially used bags of ECOBBs are not prematurely biologically activated.  Most complaints about BioBBs have to do with poor storage of partially used bags of BBs and BB Bastard has solved this problem.

.20gr - ideal for indoor gaming, a lightweight BB that ensures good performance with stock AEGs,
.25gr - the standard lower weight outdoor BB, resists wind and maintains a good trajectory in outdoor conditions.
