So I just bought the thing and I was trying to take off the stock. I thought if I pressed on this pin that it would start to disassemble but I was wrong. It's actually the pin that is connected to the elevator, and its depressed all the way in, just on one side, not the other. Because of this, I cant cock the gun. I'll attach a picture, it's the pin at the top.
I'm trying to get this pin to come back out but I don't know how.
Try posting this question in one of the more gun-specific groups.
I figured it out, thanks!
