I took my H&K MR556 to the range for the first time today and am very happy with the results. If it had a better trigger I am sure the 5 shot 100 yard groups would have been much better. As it was the first time out in the first and second groups 1 shot went off before I expected it to. So the low shot at 6 o'clock in the first group (left group)and in the 2nd group the one at 3 o'clock opened the groups up. I was a little more consistent with the last group. So the average wasn't to bad @ 0.939. Hopefully I will get use to the trigger and groups will improve.
