RZR is Nuprol's dedicated airsoft BB brand — manufactured to tight tolerances with a consistent 5.95mm diameter and spherical precision that minimises deviation in the hop-up chamber. RZR BBs are made from ABS plastic (standard) or certified biodegradable polymer (Bio range) and are polished to remove seams and surface imperfections that cause inconsistent spin.
Available in three pack formats — 2,250R or 3,350R bottle for regular use, and 6,000R resealable bag for players who go through volume at regular game days. The resealable bag format is particularly practical for field bags: fill a speed loader at the start of the day and reseal the rest. Not all weights are available in all pack sizes — see the variant selector for available combinations at your chosen weight.
BB weight guide — which weight for your build?
| Weight | Ideal for | Notes |
|---|---|---|
| 0.20g | Indoor CQB, beginners, high-volume play | Lightest, highest FPS reading, least wind resistance — not ideal outdoors |
| 0.25g | General skirmish — the most popular all-round weight | Best balance of range, accuracy, and cost for most AEGs |
| 0.28g | Outdoor field use, upgraded AEGs | Noticeably better range and wind resistance than 0.25g |
| 0.30g | Long-range outdoor, upgraded hop-up | Recommended for AEGs running 350–380 FPS with good hop |
| 0.32g–0.36g | DMR, sniper, upgraded outdoor builds | Heavy — needs a well-tuned hop-up to perform correctly |
| 0.40g+ | Bolt-action sniper rifles only | Very heavy — not suitable for standard AEGs |
