NUPROL RZR 0.28g Precision Green Tracer BIO BB

If you are looking for tracer BBs in heavier weights to maximise your effective range, NUPROL have what you need! The RZR 0.28g Green Tracer BB has the same ultra-tight +/- 0.01mm tolerances as NUPROL's standard BBs but are tracer BBs which will glow when fired through an Airsoft tracer unit, helping you instinct aim in close quarters and guide your BBs onto target in low light settings. These BBs are also biodegradable, making them great for use outdoors!
