All rights to this unique content are tied to the anareus.cz domain.GUARDER New Generation NAVY SEALS Metal Receiver is an aluminum receiver for Tokyo Marui M4 standard AEGs, suitable for building a new rifle or replacing the original receiver. The aluminum construction provides a solid base for mounting the gearbox, hop-up unit, barrel and other related parts. The set also includes a polycarbonate hop-up unit with hop-up bucking and most external receiver parts, such as the ejection port cover and charging handle. The complete receiver weighs approximately 400 g. When rebuilding an AEG, we recommend checking the fit of the gearbox, hop-up unit, magazine and front section of the gun before final assembly. Manufacturing tolerances may differ between parts from different manufacturers, so installation on guns other than the Tokyo Marui M4 Series may require fitting.
