I just googled it in every possible way I could think of, and I got Zip. It would seem that it does not exist. The only hit I got on it was the e-bay listing for the bow, so obviously I made good searches, but I got nothing. And, I will go so far as to step out on a limb, and say there is not a bow out there that can shoot 250 yards, with that one sight andset ofpins. I don't think you can have a 1 - 30 yard pin and a 250 yard pin on that one little sight. I think you should pass on this one.
