Not a bad little thing of metal... decently impressed - Radical Firearms 8.5 in. 300 AAC Blackout Upper Assembly

I was surprised at how light it was when I originally picked it up. My entire pistol comes in at 4.5 Lbs. The rail is VERY sturdy and feels amazing. I also love the way it looks. My only complaint *so far* is the quality of the Allen screws on the rail. They are sub-par. I stripped one of them out almost immediately even though I was using the correct sized bit. I ended up needing to take a Dremel to turn the Allen head into a flat head. It is currently on its way to be painted and once it gets back I will throw in all the parts, attach my Form 1 and head to the range. So far, I suspect no further issues from this upper/barrel.
