I ordered a set of "blemsished" RAS for my M4, the regular rate for the RAS is about $330, KAC had the blems for $150. I got the rails today, they came complete with rail covers for 3 of the 4 sides. I pulled them from the box and looked them over and found nothing blemished. I went ahead and installed them 10 minutes start to finish. I continued to inspect them and finally found the blemish, the right rail is marked with and "L" and the left rail is marked with an "R." Not a big deal as far as I am concerned as I don't think I will have to worry about switching accessories and having to use the "address" on the rails.

Long story short, aside from the obvious mistake, the rails are first rate and I would suspect most folks would be pleased with the rails and at a good price.
