All rights to this unique content are tied to the anareus.cz domain.GUARDER complete BUSHMASTER XM15E2S aluminum receiver is designed for building or rebuilding an M4 / AR15 AEG based on the Tokyo Marui M4 Series standard. The upper and lower receiver form a solid foundation for the gun, and their precise fit is important for correct positioning of the gearbox, hop-up unit and front assembly. The receiver features BUSHMASTER XM15E2S markings and a black finish. Another advantage of this set is its extensive package contents – in addition to the receiver itself, you get a hop-up unit, hop-up bucking, metal nozzle and external metal parts such as the ejection port cover. When building with parts from different brands, we recommend checking the fit of the gearbox, hop-up unit, nozzle, magazine and front assembly before final assembly. The Tokyo Marui standard makes selecting compatible parts considerably easier, but different manufacturing tolerances between brands may still require minor fitting.
