What is Next Gen. Rifle? Tokyo Marui's Next Generation Recoil Shock System (NGRS) helps save the realism of a gas rifle with the comfort and performance of an AEG. Using an alternate weight, simulated recoil and muzzle pull is generated to simulate a real cycling bolt. Additional features include an electronic bolt lock feature that locks the bolt again when firing the last BB from the magazine, the rifle will stop firing until a loaded magazine is inserted and the bolt stop is depressed (feature only works with magazines NGRS of Tokyo Marui). Unlike the Tokyo Marui Airsoft guns of the past, the new Recoil Shock System rifles now feature metal receivers instead of all polymers, as well as fully licensed trademarks to add to the realism of these replicas. Combined with Tokyo Marui's high in-house quality and stock reliability, these rifles are ideal for skirmishing out of the box or as the basis for high-performance projects. While the Tokyo Marui NGRS system has been around for almost a decade in the Asian market, its availability has been limited / restricted due to licensing and import issues; However, through Evike and its partners, tried and true NGRS system rifles will now finally be available in the state of the side.
