Bio BBs are an environmentally friendly alternative to standard airsoft plastic BBs. They are made from biodegradable materials such as PLA bioplastic, which helps reduce the amount of plastic left in the environment during outdoor games.

The MilGear selection includes a wide range of bio BB weights, suitable for different airsoft guns and playing styles. Lighter BBs are commonly used with pistols and CQB setups, while heavier BBs offer improved stability and accuracy in more powerful platforms and at longer engagement distances.

Our range includes high-quality airsoft bio BBs from brands such as BLS, G&G, Specna Arms and Nimrod. Consistent manufacturing quality, precise diameter and smooth surface finish ensure reliable feeding and consistent performance across different airsoft platforms.

Browse the selection and find the right bio BBs for your airsoft gun.
