Airsoft Bio BB FAQs

Are bio BBs required for airsoft?

Some outdoor fields and events require biodegradable BBs. Always check your field rules before buying ammo, especially for outdoor or milsim-style games.

Do bio BBs perform differently than standard BBs?

Quality bio BBs can perform very well, but storage matters. Keep them dry and sealed because moisture and poor storage can affect consistency.

What bio BB weight should I choose?

Choose weight based on your platform and field type. .25g and .28g are common general-use options, while .30g and heavier weights are better for tuned outdoor rifles.
