About our Bio BBs

Biodegradable BBs, also known as Bio BBs, are the ideal choice of ammo that also comes with reliability, especially if you’re playing airsoft outdoors. They are non-toxic and healthier for the environment in comparison to plastic types of airsoft ammunition – bio BB’s degrade after a couple of months whereas plastic will stay there forever.

Here at Urban Airsoft, we stock a wide range of Bio and Plastic BBs, from 0.20g all the way up to 0.43g. We only stock high-quality brands so you can feel confident that your gun won’t jam in the most crucial of moments.
