I own 2 of these rifles. I purchase the first rifle and shot my first group with Federal Match 77 grain ammo with a Nightforce 1x8x24 scope that was less than a .5 MOA at 100 yards. Since then I have purchased a 2nd rifle that is more accurate than the first. Everyone talks about this rifle but never mentions how great the accuracy is. I have shot many types of ammo most of which shoots MOA or less. I have many 2.5 " groups at 300 yards and a 10 shot group that is less than .3 MOA. Rifle 1 has 24,000 rounds down the barrel and still is accurate. Rifle 2 has my ACOG, RMR, and light and weighs 6 lbs even. I have found the AR I think is best, I have owned many top brands. I ran this rifle 2400 rounds without cleaning and without failure, shot 500 rounds in 15 minutes, let the rifle cool down and shot a 1 MOA group at 100 yards. THIS RIFLE ROCKS
