Produced by VORSK Airsoft, these Airsoft 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 0.43g 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 0.43g BBs are well within the bracket of Heavyweight BBs, and are ideally suited for Sniper Rifles and other high-power Airsoft Guns such as DMRs and Pistols (provided they have been suitably upgraded with an aftermarket HOP Bucking). If you need more poke from your replica and you have a HOP Bucking that can take it, then 0.43g BBs are a welcome 'upgrade' to your shooting experience.

To ensure the performance of these BBs they are manufactured for VORSK in Taiwan to the highest of standards. 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 two different sizes of bottles, 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 500rnd bottle is for you. Want a great sized bottle for putting in a backpack, or bag side pocket for quick access? Then the 1100rnd bottle is for you.

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. 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 suitable for Sniper Rifles and highly upgraded Airsoft Guns (such as DMRs) that have appropriate modifications to use such a BB (a high degree HOP Rubber/Bucking is recommended). The extra weight of these BBs help them stay stable in flight, less affected by leaves and wind, helping you to make more consistent shots. This does mean that they 'sink' into the ground earlier, but this can be mitigated with the use of more HOP (adding more backspin to the BBs and keeping it in the air for longer). These BBs will also sting a lot more on impact, which is good news for Airsoft Marksmen, as it can be really annoying to make an incredible shot, only for the target not to feel or call it!

If you're an aspiring marksman looking to really reach out and touch targets, (and you want to care for the environment whilst doing so) then 0.43g is an ideal BB weight for you.
