Not impressed. I will say, that this is the one and only R1 that I've gotten my hands on, so the next one I expect to be better, and maybe this was a lemon, and I hope so. Slide felt like there was grit in the rails. Trigger HAD to have been 7-8 pounds at LEAST. The sights weren't bad for a GI and I've always liked the look of the R1's clean appearance. Safety was nice and the short trigger, which I'm not a fan of, actually felt pretty good in my hand...until I squeezed it. Racking the slide without the mag in it, felt as if it were lubed with sandy glue. Very rough.
