Installed the flat trigger yesterday. While I had it apart I found a rough edge on the trigger bar where it slides against the side of the FCU. Polished it out and put her back together. I really like the feel of the trigger so far. Trigger weight is the same but take up seems to be reduced and you get more leverage which makes the pull seem lighter. I would say overall travel may be reduced slightly too. Can't wait to get it to the range later this week.
