I purchased this less than three months ago to try the long range AR thing. I just can't get used to it and prefer a bolt-rifle. There are less than 150 rounds through it, with 100 of those being the fire-forming rounds. It shot under 0.5 MOA while fire-forming and with a little bit of load development, I was able to get a couple of 0.350" -ish groups at 100 yards with Varget, CCI450s and 107 SMKs. With a better shooter and more load development, I think that there is much more accuracy potential. I am selling the upper only.
