Great sights

Love these sights. So much so, that going back to regular BUIS on another rifle is just not easy. The points on the rear sight and the angles on the surrounds help a ton to keep consistent groupings. I have both FDE and black, and I have no troubles lining up the sights on both, but as another reviewer mentions, the FDE's may be a little tougher to line up for some folks so keep that in mind. Only 2 minor negatives keeping it from 5 stars: #1 is that the night glow doesn't really work at all on both FDE & black sets that I received. Not a biggie though for me. #2 is that on the rear sights (both black & FDE), I had to shave off some of the polymer on the bottom of the flip-up-sight part because it was rubbing on the pic rail and wouldn't flip up fully, would get stuck about half way and then I'd have to push it up the rest of the way. After shaving off a bit with a razor, it flips up freely now.<br>Overall though, these are awesome sights. Get 'em!
