Airsoft BBs

Common types are biodegradable (eco-friendly), ABS plastic (standard), and metal/precision (for specialized guns). Choose based on field rules (many require biodegradable), your gun's power and barrel type, and whether you need higher accuracy or environmental safety

BB weight is measured in grams; heavier BBs (0.28–0.43 g) fly more stably and retain energy better at longer ranges, while lighter BBs (0.12–0.20 g) give higher muzzle velocity and are better for spring pistols and low-power AEGs. Match weight to your gun's power and intended use: skirmishing often favors 0.20–0.25 g, while precision or long-range play uses 0.30 g+

Biodegradable BBs are required at many outdoor fields and break down over time, reducing environmental impact. Trade-offs can include higher cost and potential for slightly less hardness or consistency compared with high-grade non-biodegradable BBs, so choose reputable biodegradable grades for reliability

Store BBs in a cool, dry place in their sealed container to avoid moisture, dust, and UV exposure; avoid mixing different weights or materials in one container. Keep them away from extreme heat and clean your magazine and hop-up regularly to prevent buildup and feeding issues

Yes—look for specifications like weight tolerance, diameter tolerance (usually 5.95–6.01 mm), material (biodegradable or ABS), and mention of polishing or tight tolerances; consistent diameter and smooth finish reduce jams and improve accuracy

No—metal BBs are not standard and can damage plastic internals, hop-up rubbers, and barrels, and are unsafe in most airsoft setups; only use metal BBs if explicitly specified for a compatible, designated system and in compliance with field rules

Prices vary by material and quality; budget options are commonly available under $50 for typical quantities, while premium or bulk biodegradable packs cost more. For casual play, dozens to a few hundred rounds per session is common; serious players often buy bulk packs to reduce cost per BB
