I had a BEAT UP 1991A1 that I received as a gift a few years ago from a friend who has since passed away that I recently rebuilt. I probably spent a good $1K on fixing it up, I know I could've probably had something much better than what I'm ending up with but I wanted to keep it for sentimental reasons. My question is now, do I take the series 80 stuff out to get that perfect trigger pull, or leave it be? The trigger is *ok* as of right now but I can't help but feeling as though I'm leaving some potential untapped.
