I bought the blemished version of this product everything came packaged nicely the only thing that could have been considered blemished was where the takedown pins had been machined you could see the aluminum a little but that’s no big deal cause it gets covered by the pins. The fit between the upper and lower is extremely tight with no wiggle at all which is perfect. I was going to take a star off because in the detent holes that hold the takedown pins some kind of sand or something was left in there from the finishing process I’d assume which caused my take down pin detent to get stuck and caused me a lot of extra work to get it out (it was not easy) but I decided to leave it at five stars because as I see it that was my fault for not checking it. Overall this is the best ar10 reciver set you can buy and you will not be disappointed. Make sure you clear your pin holes though.
