wmaguire's Review of Primary Weapons Systems MK116 MOD 2-M, .223, 16in Upper Receiver
Just built a rifle with this upper last week. Took it to the range to try out a variety of 5.56 and .223. As advertised, the POI was identical between the two. The big surprise was accuracy. Recoil with the 5.56 was noticeably more, and the groups spread out quite a bit. Then I loaded some .223. Suddenly I was shooting through the same hole at the same range. I zeroed it for 50, and at that distance the groups were sub-MOA. All in all a fine upper, but I think it likes .223 a lot better.
