here is the link to the site that I got my hind sight from

http://www.hindsightco.com/

they range from 20 dollars (which is the one I have) to 90 dollars for both front and rear sights.
I did look at some others but this one seemed to be the best for my set up
Plus they have a money back policy if for some reason you dont like it but hey they can keep my 20 bucks
I do know one thing after using this sight I will never go back to a peep sight again.
They have me hooked for life if I should live that long lol<img src=icon_smile_big.gif border=0 align=middle>
