I installed one of the CMMG 2-stage NM triggers. I had to do a little dremel grinding of some of the
bosses on it so that it would fit properly (took all of 60 seconds with the cut-off wheel). Like others,
I had to bend the leg of the hammer spring (about 5 times until I got it right
) to get it to work.
I've run about 200 rnds through it like this. Ran like a TOP!
The CMMG is a nice trigger, every bit as nice as the RR NM 2-stage in one of my AR's.
