For those looking for alternative MP5 gas blowback apart from those offered by WE Airsoft or VFC, they can check out the SRC MP5A3 CO2GBB that Mach Sakai tests in this video. The Taiwan SRC has undergone an upgrade to its CO2GBB. This enhancement includes a pressed steel upper receiver, similar to that of a real firearm, and the lower receiver replicates the early “S・E・F” model. The version is specifically designed for the Japanese market, adhering to the initial velocity regulation of 0.989J or less. The A3 model features a slide stock. This CO2 gas gun has been certified by the JASG, a manufacturing association approved by the Ministry of Economy, Trade and Industry.
