I knew that the trigger-pull of my old DPMS AR15 was heavy; much heavier than my M1917. I finally broke-down and ordered an RRA 2-stage trigger, and took a "before" and "after" measurement:

- before: 5894 grams (13 lbs!)
- after: 2227 grams (4 lbs 14.5 oz.)

This is the weight at which I can slowly lift the rifle without breaking the trigger; but a little wiggle of the rifle causes the trigger to break.

Now I this is going to tighten-up my groups!
