Inspired by our own experiences with the sport and by studying airsoft videos from various countries, we try to reproduce the sport of airsoft as accurately as possible. From Springer to Gas Blowback, Airsoft Online features all propulsion systems with their different advantages and disadvantages.In Airsoft the projectiles are small spherical plastic pellets. They are influenced by aerodynamic factors such as drag and wind. We have developed a custom physics system, which is based on real fluid dynamics, resulting in realistic BB-trajecotries during gampelay.For some experienced airsoft players, tuning airsoft-weapons is a hobby that complements the sport. The performance of an airsoft gun is dependent on all internal components. Improve the hop-up for increased accuracy. Install a shorter barrel for more stealthy gameplay. Or switch to a red dot on your sniper rifle to show off an aggressive play style.
