Some folks get real sensitive about their "sacred cows." Funny thing is, many of the same folks don't even own one of the sacred cows they're defending. I do not own any BCM products....other than a couple of spare extractors. I do own a Colt, a BM, a RRA, and a Spikes. Based on what I read and my conversations with others, I would buy / own a BCM product if I wanted another AR. They have a terrific reputation. But even the best organization can and will put out a less than stellar product on occasion, there are no exceptions.
I hope they get you fixed up quickly.
