"Does not fit on my DPMS AR-15, it moves after it is tightened as tight as I could with a screw driver. Hoping for a return"

"Mounted easily enough to the rail. Didn't feel like I could get it tight with just fingers. Didn't come with any information in the box. Disappointed it was made in China. While trying to zero, adjusted easily enough."
