I've been pretty happy with CMC single stage 3.5# triggers in nearly all of my ARs. I got a hold of a patrol/duty 4.5# but can't really tell the difference. I've tried Geiselle's and they seem worth it and would probably use them if I hadn't started with CMC. I just like keep most things the same.
It wasn't my intention to derail the thread with Blowwtach negative experiences. I was just trying to help rather than have someone paying an extra hundred for MRO and mount. The Larue deal is equally economical. Now back to the MRO.
Yes, that's a good deal if you like Larue mounts, but I don't. Sorry I was just posting a decent deal. I personally don't get all wrapped up in principle buying accessories for tools.
