In the m733 video on mechbox.com he didn't seem to even touch the fire selector.
I'm meaning on how to reattach the fire selector? The one that you flip to change from safe to semi or to full auto.
Maybe I should post some pictures...
1. In the first picture is the piece rounded with a red circle, I'm trying to figure out which way this goes in.
2. The picture of the metal body.
3. That way I'm trying to attach it, but when I attach it that way, it's too stiff and the fire selector wont move. But when I loosen the screw, the fire selector moves but the metal piece doesn't.
