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 0.25g 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 BB are designed to work in any Airsoft gun, but perform at their best in beginner and low power Airsoft replicas under 350fps. Whether you're new to Airsoft, playing indoors, or looking for BBs for your Spring Powered Airsoft replica then these are the BBs for you.

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.
These weight BBs are perfect for those Airsoft Skirmishers who are looking for high quality and top of the line BBs for their Airsoft Guns firing under 350fps. These BBs perform best in in-door games, or in low wind conditions, with this weight typically being used by Airsoft sites as a base line weight for chrono'ing and testing guns. If you're looking for a high quality BB which does not compromise on performance due to its materials then VORSK Bio BBs are the perfect choice.
