NUPROL RZR .30g Bio-Degradable Environmentally Safe 6mm Airsoft BBs

Site-safe. Precision-made. No cleanup guilt.
NUPROL RZR Bio BBs deliver the same ultra-tight manufacturing standards as NUPROL’s standard range, but with the added benefit of biodegradable construction. Manufactured to a precise 5.95mm ±0.01mm tolerance, these BBs offer consistent feeding, improved accuracy, and reliable performance across AEGs, gas blowback rifles, and spring platforms.
 
Made from a biodegradable polymer, RZR Bio BBs are accepted at even the strictest airsoft sites. That means you can focus on your game rather than worrying about site rules or post-game cleanup. They are designed to break down naturally over time when exposed to environmental conditions, making them a responsible choice for outdoor skirmishing.
 
Smooth, highly polished and tightly controlled during production, these BBs minimise jamming, reduce barrel wear, and maintain stable flight characteristics.
