Hey folks, hope someone here can help. I'm building my first AR (Mega lower w/ J&T CAR kit) and I can't get the trigger pin to go all the way through. It seems like the disconnecter isn't going down far enough to line the holes up. I'm sure I'm using the right spring (one end wider). Even with the trigger out of the lower I can't get it to go. I got the front pivot pin in with almost no problems, but this is driving me crazy. Also, My kit seems to be missing the buffer pin spring. Anybody know what size it is so maybe I can get a replacement locally?
Thanks
John

I figured it out, but I still don't have a buffer pin spring. Crud. Everything else went together with no problems at all. Looking forward to shooting this thing.
