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!

Full description


These 0.28g Green Tracer BIO BBs are constructed from a biodegradable polymer and measure 5.95mm in diameter with a tolerance of +/- 0.01mm, making them a great choice for improved accuracy and smooth, consistent feeding compared to cheaper alternatives. You are what you eat, and the same is true for your Airsoft gun. To get the most out of features such as adjustable HOP-up units and tightbore inner barrels, high quality ammo is an absolute must!

These BBs are approximately 0.28g in weight, making them great for outdoors skirmishes and setups with upgraded HOP-up parts, giving superior stability, wind resistance and foliage penetration than lighter weights. When fired through an Airsoft tracer unit, these BBs will glow green and illuminate the trajectory of the BB allowing you to steer your rounds onto target easily and can be very useful for snipers operating in low light.

Being biodegradable means these BBs will be allowed at even the strictest Airsoft site which mandates biodegradable ammo, so you don't need to miss out on tracer functionality or lose potential range by choosing lower weights. 

The ultra-tight 5.95mm +/- 0.01mm tolerance of RZR BBs makes them great for tightbore barrel setups, guaranteeing smooth feeding with every shot. 0.28g is the go-to weight for those who have upgraded their HOP-up unit and want to take full advantage of it, so if this is you and you skirmish in low light conditions with a tracer, get yourself some of these!
