27 Oct 2017
Mach Sakai takes another MP5-J AEG and it's the CYMA CM049J. This has an electric blowback feature. The standard CM049J has an initial muzzle velocity of 440fps but this version has been downgraded to meet Japanese limits. Mach Sakai checks it out for operation, externals, and performance in a steel challenge.
