Update: We are having an issue with attempting to remove the errant trigger guard roll pin. It just ain't coming out. Even attempting to punch it out with a roll pin punch isn't working. And I don't want to force it that way any longer for fear of damaging or tearing up the dog ears/lower. Right now, they're OK.
I have taken out the opposite roll pin screw in an effort to not cause that damage as well. If I then jiggle the trigger guard back and forth, it's tight, but it does move and the roll pin moves with it (slightly). My next step is to attempt to loosen the pin with some penetrating oil (unless you think I shouldn't since it may damage the finish). I'll then try to remove it with my new roll pin pusher toll. Right now, that's not working as I can't get it to anchor properly.
At EOD, if it means I have to sacrifice the trigger guard to save the lower and its dog ears, I'm willing to do that. It's only $19.00 and it's non- FFL, so I can get another. I can't get another lower just as easily. Whatever help you can offer to help me resolve this would be greatly appreciated.
Further Update: The penetrating oil did the tricik! Just a small squirt and 15 min. later, some light taps and it came right out. I was then able to use the roll pin pusher to put in the new pin.
All is well now and the build continues. Now I'm focusing on installing the barrel, delta ring and gas tube, etc., It will be fun trying to align all the pieces of the delta ring. I guess I'll use a separate tube to ensure they stay aligned as I mount the delta ring. Then comes torquing it properly. I have the torque wrench etc, so I'll watch some more YouTube videos.
Onward!
