Dumb question, but does the retaining pin for the firing pin go in enough so that the rubber o-ring is in the hole completely? It doesn't seem to seat, and I have put plenty of pressure on it. I did a search and saw a video post by the artist formerly known as amsdorf, and someone asked a similar question, but "almost flush" seemed to be the only answer. Anyway, I thought I'd ask before I brought out the hammer (jk). Thanks fellas!
