Bigbulls - I agree the overall concept and design is real nice, but it needs some improvement.

Cornfed & Thaninator - I have hex nuts that would of worked, and if I would of kept the sight I probably could of fixed the dove tail problem. I really wanted to keep the sight, I like the v-pin set up also, and in the short time I shot the sight it does give a nice field of view. It also set up on the target well. But those pins are junk IMO, and that was the real killer for me. If they beef them up I would check the sight out again.
