Bio BBs

If you are looking for tracer BBs in the go-to skirmishing weight, 0.25g, NUPROL have what you need! The RZR 0.25g Green Tracer BIO BB has the same ultra-tight +/- 0.01mm tolerances as NUPROL's standard BBs but are green 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. 

If you're an outdoor or nighttime skirmisher with a long-range-focussed setup, Delta Armory 0.32g Diamond 6mm BIO BBs are what you need to feed it! These high-grade BBs are made from a biodegradable polymer and glow green when shot through an Airsoft tracer unit. Their tolerances are exceptionally tight, boasting only +/- 0.01mm deviation between individual BBs and the surface of each BB is polished to perfection for reliable feeding and maximum accuracy.

Supplied in a resealable bag containing approximately 3120 BBs, these BBs have a guaranteed weight difference not exceeding 0.01g, extremely precise standards. If you need a bio BB with the perfect combination of heavyweight, affordable price and tight tolerances, Delta Armory's 0.32g Diamond 6mm BIO BBs are exactly that!

The 0.58g BIO BBs are 6.44mm in diameter, which means they are only compatible with snipers that have been upgraded with the Novritsch ''Full thrust'' kit and also require a Novritsch ''Full thrust'' magazine. The higher surface area of the 6.44mm BBs means the force of the BB when it hits is spread over a bigger area. This results in the 0.58g 6.44mm BB causing no more damage than a standard 6mm BB when shot at equal power and range. These white BBs come in a resealable bottle which contains approximately 420rnds, plenty of ammo to hit those shots from across the battlefield and being white means they can be easily tracked due to their contrast with the colours of mother nature.

The heavier weight of these BBs means they will travel further, provide better accuracy and maintain more stability in the wind. This provides a superior sniping experience and allows you to hit opponents consistently from extremely long distances. These BBs are biodegradable, which is perfect for outdoor skirmishing. What's better than a veteran sniper? An environment-friendly veteran sniper!
