I've done a lot of research on this gun, and everything about it is completely legit! It's basically the Tokyo Marui G18C, just made by CYMA without that Tokyo Marui cost. Of course, it isn't made with the same quality, but this thing is definitely of comparable quality for it's price tag! This AEP is the way to go for a reliable sidearm in those tight situations when your primary has failed you, and you need to quickly light up your adversaries! Definitely use with high quality .20 or .23 bb's, don't use the ones that come with the gun.
