Had to fit pins - Strike Industries Scorpion Universal Reflex Mount for GLOCK

the mount itself seems well made but I had to fit 3 out of the 4 pins to mount the red dot sight and yes I used the pins I was instructed to. I had to chuck the small pins in a drill and sand until they fit snugly in the holes. There were no instructions on how to assemble all this but I figured it out. I think Strike Industries could do much better.
