Madbull 0.20g Bio Tracer BB PLA 2000rds

The Madbull 0.20g Bio Tracer BB PLA 2000 rds are very well polished bb's and highly recommended for the tracer enthusiast precisely because they are also biodegradable.

These Tracer BBs are white in colour and available in 0.20gr and 0.25gr.
Madbull also has these BBs available in the red colour but unfortunately these are not biodegradable and only available in 0.20gr.
