I am changing out a upper receiver.All was going well till the FA.Is there a trick to knock out the roll pin?

Also,i could only get 35lbs on barrel nut.75-80lbs would not line up.Sound correct?

Thank you.

should just be able to tap the pin for the fa pretty easy, may need to push it in slightly to relieve some pressure on the pin

and 35lb sounds fine to me. 80 is top end.
