Yes it is. Except for a few parts like the orange tip. But yes, it is a metal gun, it's very heavy by the way, weights almost the same as the real ones :)
I have 3 of this guns right now. I'm out so I can't answer the private message you sent me, I'm using the listia app right now. Just email me at mdshtc@gmail.com and I will tell you what we're going to do. It's an easy fix, don't worry :)
