Description
G&G Competition Grade Bio 0.20g BBs – 2,000 Rounds (G-07-147)
These are G&G Competition Grade Bio 6mm airsoft BBs in the 0.20g weight, a pack of 2,000 rounds under the code G-07-147. A smaller pack like this is ideal for pistol players, for trying G&G’s Bio BBs before buying a kilo, or for keeping a reserve for sites that require biodegradable ammunition.
G&G Armament is a Taiwanese airsoft manufacturer, best known for its AEGs, which also makes a wide range of BBs. Its BBs are sold in several grades, including P.S.B.P., Competition Grade, Bio and tracer, with product codes in the G-07 series.
Choosing the weight
A 0.20g BB is the usual starting weight for stock AEGs, gas pistols and spring replicas. It is light enough for replicas at typical out-of-the-box power, which is why most new players begin with it before trying anything heavier.
Lighter BBs leave the barrel faster but slow down sooner and are more easily pushed around by wind, so 0.20g is at its best indoors, in CQB and at short to medium woodland ranges.
Bio BBs
Many outdoor sites, especially woodland ones, ask players to use biodegradable BBs, so check your site’s rules before game day. Bio BBs are meant to break down over time, which also means they should be kept sealed, dry and away from heat until you use them, and used within a sensible time once the pack is opened.
Pack size
Two thousand rounds is plenty for a pistol-heavy day or a short session with an AEG. If you play regularly at a Bio-only site, the same range is also offered in 1kg bags.

Compatibility
Suitable for 6mm airsoft replicas whose power and hop-up suit a 0.20g BB. If you change weight or brand, re-adjust your hop-up and have your replica chronographed, as BB weight affects muzzle velocity and energy. Check your site’s rules on BB weight and type, as some sites ask for biodegradable BBs.
Care and maintenance
Keep the container closed between refills and store your BBs somewhere cool and dry, out of direct sunlight. Moisture and grit are what cause most feeding problems, jams and hop-up rubber wear.
Never reuse BBs picked up from the ground, avoid mixing weights or brands in one magazine, and give magazines and speedloaders an occasional wipe so dust is not carried into the hop-up.
Who is it for?
For players with stock AEGs, gas pistols and spring replicas who need a manageable supply of biodegradable BBs.
Please note: Always wear suitable eye and face protection when using airsoft replicas.
