1st: I'm trying to figure out which hole Disconnector spring goes in. The on closer to the actual trigger or the one farther back.
2nd: I am really displeased with the finish on my trigger. One side on the rear has unfinished metal, is pourus around the lip. I'll post pictures later. I'll have to the dealer and tell them I want another, cause it just aint gonna cut it, looks real cheap and ugly.
It's the hole near the rear of the trigger base - I think ARF has a parts diagram you can look at to help you out, so does Bushmaster and other companies. As to the crappy metal finish, sounds like it was cast poorly. Either get another one or smooth it yourself with sandpaper, dremel, or whatever and repaint it. Triggers aren't that expensive, you time and effort may be cheaper though.
