  • Heavyweight Bio BBs

Produced by VORSK Airsoft, these Airsoft BIO BBs are precision engineered 6mm BBs which are designed to be used in a wide range of Airsoft guns and replicas. These BBs are part of the VORSKs brand new range of Airsoft BBs ranging from light weight BBs for beginner Airsoft players, all the way up to super heavyweight BBs for professional players and snipers.

These particular BBs are BIO 0.36g BBs which are created from biodegradable materials so that they will gradually break down with time when exposed to natural environments. Touted as a more environmentally friendly BB, they are sometimes required by certain Airsoft sites to play. 

These 0.36g BBs are seated well in the middle of the Heavyweight Scale, meaning that they're incredibly precise when used in a well-tuned Rifle. This extra weight helps them stay stable in flight, less affected by the wind, leaves and branches etc, which makes them a great choice for Sniper Rifles and DMRs that need to make sure that every shot hits (and that the hit is called when it does land).

  • Biodegradable!
  • Heavyweight BBs
  • Compatible with Novritsch ''Full thrust'' platforms


The 0.58g BIO BBs are 6.44mm in diameter, which means they are only compatible with snipers that have been upgraded with the Novritsch ''Full thrust'' kit and also require a Novritsch ''Full thrust'' magazine. The higher surface area of the 6.44mm BBs means the force of the BB when it hits is spread over a bigger area. This results in the 0.58g 6.44mm BB causing no more damage than a standard 6mm BB when shot at equal power and range. These white BBs come in a resealable bottle which contains approximately 420rnds, plenty of ammo to hit those shots from across the battlefield and being white means they can be easily tracked due to their contrast with the colours of mother nature.

The heavier weight of these BBs means they will travel further, provide better accuracy and maintain more stability in the wind. This provides a superior sniping experience and allows you to hit opponents consistently from extremely long distances. These BBs are biodegradable, which is perfect for outdoor skirmishing. What's better than a veteran sniper? An environment-friendly veteran sniper!
