Got around to mounting and qualifying with this upper a couple days ago. It's got an issue with the FSB, seems to be canted. This is what the rear sight looks like once it is zeroed...

| Well that right there is the same exact problem I have with my Premium 16" M4 upper. I emailed PSA and they sent me a shipping label. I packed it up and shipped it the other day and they should get it back today. My Magpul MBUS was cranked all the way left also. I dealt with Alex Rios and he said they are going to check it out. Tagging this for update. |
