Quality as expected so far - Radical Firearms Complete Upper Assembly 16 inch 5.56 M4 Contour, A2 Flash Hider, w/BCG and CH

I’ve always trusted Optics Planet to provide great service! This experience is no different than any other that I have had with them. Great! Now, I’ve only taken this upper to the range one time since I got it about a week ago. I can say that it functioned flawlessly through every round. I was even bump firing through most of the about 150 rounds sent down range. No visible flaws upon removing it from the packaging! Packaged very carefully! I did clean and lube it before taking it out to the range. It was lightly oiled, but I did add more in certain areas! There was also a small amount of, what seemed to be carbon build up. I’m assuming that perhaps the upper was test fired and that’s why there was a tiny bit of carbon. At the moment, very satisfied! Awesome upper! Fun to shoot!
