I got a couple of uppers for my wife to experiment with, because they were cheaper than I could build them. They worked for defining what she wanted, and now I can build the right one right, and not really be out near as much in the process. I didn’t expect them to be top tier. Hell, I’d have been surprised if there weren’t some sort of quality issues at that price point. One of them seemingly had a extremely tight throat.....can’t eject a live round by hand with most AMMO, without leaving the bullet in the throat. Works fine when firing....so far, but that’s a disaster waiting to happen, so it went back to BCA. BCA sent it back with a letter saying it shot fine. No [bleep]....until it doesn’t. Peeved? Sure. Great CS turnaround. Complete QC ignorance. However, I can say they met my expectations. LOL. Most issues aren’t going to keep anyone from plinking or hunting with them, for the average AR owner. Folks that aren’t that and are into the quality end of the spectrum are likely to be disappointed. Your $ is your $. Do what you like and damn what others think. You’re the only one has to live with it.
