One day, the GBLS developer realized that the Airsoft guns that he purchased and believed to be different were actually based on the same gearbox. Even though manufacturers claimed every time that “we are different and our technology is innovative”, they turned out to be disappointments. His passionate opinion is that airsoft is not about just simply shooting BBs at your opponents. Airsoft has been around for more than 30 years but the technology only progressed by inches. We, as players, spend hundreds, if not thousands of dollars, purchasing gear in preparation for airsoft games, and yet we still play with antiquated airsoft guns. This really motivated GBLS to pursue how they can make their beloved game more realistic. DAS is an acronym for “Dynamic Action System”. DAS is an AEG that provides the realistic features of GBBR that was previously unattainable in AEG by inventing a mechanical firing system that eliminated electronic control.
