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 0.28g 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. 

This weight of BBs is specifically designed with a higher weight to allow it to punch through light wind and bushes with ease, allowing you to be more effective in outdoor games. These  BBs perform best when used in Airsoft guns between 300fps - 400fps, and are great in replicas which have had upgrades or come with an extremely good hop out of the box.

To ensure the performance of these BBs they are manufactured for VORSK in Taiwan to the highest of standards. Although these BBs are designed to be Biodegradable they suffer no loss in quality or performance over standard BB types. The BBs are designed and sorted to the highest of tolerances to ensure they travel as stably as possible through the air. Each VORSK BB is made to 5.95mm with a production variance of only ±0.01mm, which are some of the highest tolerances available on the market to date. Once made each BB is triple polished for enhanced flight, meaning there are no small imperfections which would cause drag and deviation in the flight path of the BB.

These BIO BBs come in multiple different sizes of bottles and bags, allowing you to pick the perfect amount for your play style. Want to take the BBs in-game in a magazine pouch, or simply want to test them out, then the smaller 1100rnd bottle is for you. Want a great sized bottle for putting in a backpack, or bag side pocket for quick access? Then the 2000rnd bottle is for you. Found the perfect Bio BB for you, and want to purchase larger volumes of BBs? The 3600rnd Bottle and 1KG bags are the best choice!

To make sure the BBs are just as fresh as when they were first produced each bottle comes sealed with a foil top to keep them as Airtight as possible. The bags are also heat sealed to keep them fresh, with a re-sealable opening to prevent your BBs from escaping when you put them in your kit bags and backpacks. To make it easy to open the bottles come with a large screw top lid to make them easy to open even whilst wearing gloves.

This weight of BB is great for any Airsoft player who is a regular player with an upgraded gun or high quality replica. Using 0.28g BBs is seen as a step up from lower weight and is a milestone from player to regular skirmisher. 0.28g BBs have the best weight to performance ratio for outdoor style play, allowing you to really line up your shots with less worry about wind and foliage. Don't worry about compromising on quality for BIO, VOSRK excel in all conditions.

Special Instructions

Ensure that if you're going to be using these at a CQB site you first make sure with the site organiser that you are safe to do so. Getting hit with a 0.28g BB stings outdoors, but will absolutely suck indoors, so some sites do not allow them. Please ensure you talk to the marshals should you look to use 0.28g at a CQB site.
