Produced by NUPROL, these Airsoft Tracer BIO BBs are precision engineered 6mm BBs which are designed to be used in a wide range of Airsoft guns and replicas. These BBs are part of the new RZR range of Airsoft BBs ranging from lightweight BBs for beginner Airsoft players, all the way up to super heavyweight BBs for professional players and snipers.

These particular BBs are not only BIO BBs, but are also Tracer BBs. These BBs are created with two purposes in mind. Firstly they are created from biodegradable materials so that they will gradually break down over time when exposed to natural environments as well as being infused with special materials to allow them to glow in the dark. Touted as a more environmentally friendly BB, they are sometimes required by certain Airsoft sites to play.

This weight of BB are designed to work in any Airsoft gun, but perform at their best in beginner and low power Airsoft replicas under 350fps. Whether you're new to Airsoft, playing indoors, or looking for BBs for your Spring Powered Airsoft replica then these are the BBs for you.
