Hi, I've got a JG m4 and need to know the name of a part and where I can get a new one. It's the piece that actually holds the outer barrel to the receiver. I stripped the threads with the hex screw by over tightening it. (stupid pot metal)
It's part WA-16 in the picture.

I've tried searching but its difficult to do when you don't know the name, which is what I'm searching for. Thanks in advance.
