I don't believe they're selling these barrels as stand alone any longer, so the public isn't at risk and I'll be a bitch as long as I please. My primary goal here was to see if this wise community had information to the contrary of my cursory understanding of BA's lines and capabilities.
I'm giving them one more chance to get this right next week. If the answer is they are going to use BA barrels in lieu of what I supposedly bought, I'm at the point of saying they can just ship me back my uppers without barrels, I'll take the hit and chalk it up to experience.
Once I have word from them as to the course of action, I'll fill in the blanks... Which were "not 3rd party sourced".
