Mach Sakai checks out an AEG, the Kanego Airsoft K4A1 Elite AEG that comes with blowback and recoil. This looks like a rebranded BOLT Airsoft AEG as it uses the BRSS or the Bolt Recoil Shock System but with Colt markings and is made to meet the Japanese airsoft market. As always, he puts through the usual paces of checking externals and operations then ending it with a quick steel challenge.
