Poor manufacturing quality - Aero Precision AR15 5.56mm Bolt Carrier Group

Bought this BCG because it was highly recommended; however, the product does not live up to the hype. Not sure if they are rushing to get products out the door or what, but the firing pin retaining pin would not reseat after I disassembled the BCG for an initial cleaning. Also, edges of the gas key were rough machines and not properly deburred - very rough finish. Overall, if I’m going to spend this level of money on a product I expect it to be completely GtoG out of the box! Now, I’ve lost precious time by having to return this crappie BCG and try and get another one. Well, you can only rip me off once.
