Quality isn't what it used to be - 2A Armament Titanium Regulated Bolt Carrier, Bolt Carrier Group (BCG)s

Received my package today. My package was damaged and the key that is suppose to come with it for the adjustment is missing. On the tail end of the carrier has a stain or the coating used is blemished. The cam pin is all pitted and the bolt has brass particles like as if it has been used before I bought it. There is even wear on the bottom of the carrier as if it had been installed into an upper. Seriously considering returning.
