OK updates, I got that little piece back in, found out where it goes from a great VSR visual guide. Now I know the issue is mag/feed related. The first shot out of a mag fires every-time, but after that its either double feeding, or something, because it dry fires and when the mag is removed a bb falls out. Help?
EDIT: I got it working well after taking apart and putting the hopup back together a few times. The culprit was a small u shaped piece that helps with feeding, I read somewhere if its not JUST right, you can have problems. Thanks for all who helped.
