Produced by VORSK Airsoft, these Airsoft Tracer 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 not only BIO BBs, but are also Tracer BBs. These BBs are created with two purposes in mind, being created from biodegradable materials so that they will gradually break down with time when exposed to natural environments as well as being infused with special materials to allow them to glow in the dark. Touted as a more environmentally friendly BB, they are sometimes required by certain Airsoft sites to play.

These particular BBs are standard 0.25g BBs which are designed to work in any Airsoft gun, performing best in Airsoft guns which fire between 280fps - 370fps, and are the go-to weight for any Airsoft skirmisher looking for an the perfect all around weight for a standard AEG. Whether you're new to Airsoft, or a regular skirmisher, this weight of BB will most likely be your go-to BB weight, and is the most commonly used by Airsoft players.

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 Tracer BBs 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 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 have got their hands on an Airsoft Tracer Unit and have an Airsoft Gun which fires between 280fps - 370fps. These BBs perform great in both in-door and outdoor scenarios, with this weight typically being used by most Airsoft skirmishers as their go-to weight for BBs.
