Mach Sakai checks out the MTR-G or the Gold Edition of the Tokyo Marui MTR16 Gas Blowback Rifle if it has some improvements with the Frontier recoil buffer over the originaL MTR16... "The bullets may hit and scatter inside with a long sap. Frontier's original recoil buffer is the best! I tried whether the suppressor is effective if it is long or if it is effective with a gas blowback gas gun."
