I know how hard it can be to mount a stubborn colt frag. I tried it all but the toothpick worked the best for me. Get this, I couldn't even spear mine horizontally and jam the toothpick in the rock. Eventually it just split at the bottom and floated away! I got aggressive, almost mean. I just jammed the toothpick right through the sucker as if I wanted to kill it, shoved the ends of the toothpicks inside holes in 2 pieces of LR, then squeezed the LR together until the colt was almost flattened. This way both the 2 pieces of LR, AND the toothpick kept it in place. It didn't budge after that! Eventually it just grew up and out. Sounds mean, but it worked for me
