Nice looking Sight, a bit on the high side and it could be worth every dime of it. Check out the MENDOZA Sight, they make 2, 1 open blade and one peep sight. Fits on almost any 11 mm flat dovetail. Price with shipping is about 1/2 of the one you have listed. I got Mendoza to send me 1 open blade when I told them I was going to use it and test it on a GAMO CFX. I shoot with a scope, but I was impressed with the MENDOZA as a replacement for the GAMO Sight and I even tried it on my RWS Diana 34 Panther, appears to work well on any thing it is used on if you like using these types of sights. Just my 2 cents worth.
