Ok, for those of you that want to know. You could tell a difference in recoil, with out it, it did kick just a bit more. But with my loads of 43gn of 4064, behind a 150gn hornady interlock sp. It just didn't quite have enough bang to make it cycle consistently with the weight. I remove the weight, grouping improved to sub moa. Gonna have to do some more trigger work on it. Somebody, before me, took a little too much of the sear. It shoots on the trigger pull stroke, and trigger release stroke. Sometimes.. Because the disconnector, disconnects, before the sear has control of the hammer. I am most likely going to get a match trigger anyway. If it shoots this good, like it is. I think its worth moving forward with. Recon? I'm thinking match trigger.. Get rid of the flash hider, install a brake. Then move on with developing a load for it. What do you guys think? Is this a good order to go in, on one of these AR's?
