I have a cmc drop in flat blade single stage trigger for a ar15 or ar10, it pulls right around 3.5 pound concistently. I don't use it much because of the flat blade. I bought it to test and see if i would like flat blade trigger. Letting it go for cheap incase someone else out there want to do the same and so it sells. Asking 70$ shipped to your door in the lower 48. They come with a lifetime warranty through cmc as well.
