I assembled my first stripped lower tonight. Everything went smooth except for the damn bolt catch roll pin. Once I finally got it started and got everything aligned I had to hammer the hell out of it and finished the last bit off with the vice grip method. That worked great except for the last clamp to flush up the roll pin with the receiver when the vice grip ate through the plastic tips on it and left a nice little shiny spot. Then I got to the trigger guard roll pin which started good but I had to hammer it in so hard I bent my punch. It went in without issues though.
So are those roll pins that hard? It was a DPMS kit on a Spikes lower. They seemed bigger than they needed to be, especially the bolt catch roll pin. I ate up some finish trying to get it started because it was bigger than the hole and I was trying to hammer it in, is there a better way for that?
I used the kit they guy sells on the EE and it worked fine.
On the good side I the rest went fine. I've changed grips and stocks before so those steps were easy. I was dreading the FCG for some reason and it was probably the easiest thing to go in. And yes, I put the safety in it.
