Description
Ares Amoeba Diamond Precision 0.28g BIO (3570) 1 Kilo BB’s
This is a 1kg pack of Ares Amoeba Diamond Precision Bio BBs in the 0.28g weight, containing 3,570 BBs. It is a good-value way to buy a popular mid-weight BB for upgraded AEGs and gas rifles, with enough for several game days.
Ares is a Hong Kong airsoft manufacturer, and Amoeba is its modern sport-styled range of replicas and accessories. Diamond Precision is the name used for its BBs, sold in several weights and pack sizes so you can stay with one brand as your replicas and play style change.
Choosing the weight
A 0.28g BB is a popular mid-weight for upgraded AEGs, gas rifles and some pistols. The extra mass helps it hold its line in a breeze and carry its energy, but it needs a replica with enough power and hop-up to lift it, so it is not ideal for low-powered or very short-barrelled guns.
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 pack sealed when you are not using it and store it somewhere cool and dry, out of direct sunlight. Damp or dirty BBs can swell or pick up grit, which leads to jams and inconsistent flight and can damage a hop-up rubber. Never reuse BBs that have been dropped on the ground, and wipe out your magazines and speedloader now and then. Bio BBs in particular should be kept dry and used within a sensible time, as moisture can affect them.
Who is it for?
It suits players with upgraded or higher-powered AEGs and gas rifles who want a steady mid-weight Bio BB in a larger pack.
