Poor quality product - Guntec USA AR .308 Cal Gen 2 Multi Port Compensator

Optics Planet has been great whenever I have placed orders in the past. However, I'm very disappointed with this break...I ordered two for some AR10 builds I was putting together. One of the two breaks was so poorly machined that it actually had holes on the bottom of the break where they milled it down too much! I don't know how this got past quality control because someone had to paint it and someone else had to pack it. Very disappointed! Sending them both back. I'll update as soon as I contact Optics Planet and see how easy or difficult that experience is.
