I just put one of these in my AR:
4lb Velocity AR Trigger at
This cost me $150 shipped to my door. Last week I used it in a 4 day class where we fired about 500 rounds. I can't say enough good things about this trigger. Not expensive, super crisp and I can't feel any creep or over travel. I'm sure they are both there, otherwise the trigger wouldn't work, but I can't feel it.
