  • 0.25g Weight - 2200rnd bottle or 6000rnd bag

If you are looking for tracer BBs in heavier weights to maximise your effective range, NUPROL have what you need! The RZR 0.25g Precision 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 available in both red and green, but if you want red tracers make sure you check your tracer unit can light up red tracer BBs as not every unit can. 

Full description

Optional Extras...


These 0.25g Precision Tracer BBs are constructed from 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 0.25g in weight, making them great for almost any Airsoft gun and both indoors and outdoor skirmishing environments. When fired through an Airsoft tracer unit, these BBs will glow and illuminate the trajectory of the BB allowing you to steer your rounds onto target easily. These BBs are available in both red and green colour, but if you want to get the red option make sure your tracer unit is capable of lighting them up as not every unit is suitable for red tracers. 

Being 5.95mm +/- 0.01mm makes them great for tightbore barrel setups, guaranteeing smooth feeding with every shot. If you play a mix of CQB and woodland and you don't like to overcomplicate things, 0.25g BBs are a fine choice made all the better with the psychological warfare advantage gained by using tracer BBs!
