Description
Ares x Amoeba Diamond Precision 0.30g (Bio – Bottle – 3300)
These are Ares x Amoeba Diamond Precision Bio BBs in the heavier 0.30g weight, with 3,300 in a bottle. They are aimed at upgraded and higher-powered replicas, where a heavier BB can give a steadier flight and better resistance to wind.
Ares, the Hong Kong airsoft maker, sells BBs under the Amoeba Diamond Precision name. The range covers light, mid and heavy weights, so you can pick the one that suits your replica and buy more of the same when you run low.
Choosing the weight
At 0.30g this is a heavier BB, suited to upgraded AEGs, gas rifles and DMR-style setups with enough power and hop-up to lift it. Heavier BBs are less affected by wind and keep a steadier line, which helps at longer range. In a low-powered replica they can drop early, so check your setup first.
Bio BBs
These are listed as Bio BBs. Many outdoor sites, especially in woodland, ask players to use biodegradable BBs, so check your site’s rules before you go, and keep a pack ready for games where they are required.

Compatibility
Suitable for 6mm airsoft replicas. Choose the weight to suit your replica’s power and hop-up: if you change weight, adjust the hop-up and have your replica chronographed, as BB weight affects muzzle velocity. Check the weight limits at your site, as some set limits for certain replica types.
Care and maintenance
Keep the lid on between uses and store the bottle somewhere cool and dry. Moisture and dirt are the enemies of consistency, so do not load BBs that have been dropped or got wet, and give magazines and loaders an occasional clean to stop dust being carried into the hop-up. Bio BBs in particular should be kept dry and used within a sensible time, as moisture can affect them.
Who is it for?
For players with upgraded AEGs, gas rifles or DMR-style replicas who want a heavier BB for steadier flight, and who play at sites that ask for Bio BBs.
