Reviews & Ratings for Radical Firearms Complete Upper Assembly 16 inch 5.56 M4 Contour, A2 Flash Hider, w/BCG and CH — 2 reviews — Page 1

1st time buying a Radical Firearms upper. Upper came nicely bagged, covered in heavy oil, inside in a foam padded box. The barrel and bolt are nitrided so that is a plus. Loved the FCR handguard, very light. However, here are my gripes:

1. The color was not consistent across the handguard's Picatinny rail. It looks like during the anodizing process there were some artifacts. The middle up the Picatinny looks almost brown-purplish in some areas. Not a deal breaker, but I wouldn't have kept if I was building for someone else.

2. Machining marks can be seen at the bottom of the retaining pin blocks. Again, something you would not see once it is matched to a lower, but not as refined as other manufacturers.

3. Lastly, the barrel nut. My upper came with a SOCOM barrel, which is very nice but heavy. I bought a 14.5" pinned Gunner from FAXON to replace the barrel, and to my surprise, the barrel nut required a large wrench (~ 30 mm) or a crescent wrench to remove. No way of knowing the correct torque when using these.

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!
