Just a heads up, I was looking for the parts to turn my AR15/M16 CMMG conversion kit into full auto. I called the # on Ciener site and the message is to the point and looks like there would be no customer service AT ALL, if something went wrong. At this years Shot Show I remembered someone saying he was in jail. So I came up with these links during my search.. I would not send this guy 1 penny!!!
