Here's a review of the "Japanese" version of the KWA AK74M gas blowback rifle by RA Tech. In a way, it is indeed a KWA GBBR, but we'll call this the KSC AK74M since that's for the Japanese market which also means it follows the local laws. This is System 7 Two Gas Blowback Rifle so check the full video as a walkthrough, recoil, and chrono tests are done.
