RS-CREED-3-WE Creedmoor Vernier Tang Sight, for Mid Range competition, with 3" elevation and windage, plus true Vertical alignment . . . $64.95
If you check this on the Track of the Wolf web , catalog it gives a bit morer info. Not a real expensive sight . If you are looking for some pinpoint shooting you may want something more. But it suit me and my pocket book!. I put it on myself , not a good idea. But if you are handy at all it can be done . I tried to just file down the base of the ladder to fit the original base on the rifle but couldn't get the spring to cooperate so I inlet the complete new sight base. I had to use wood screws instead of the metal ones which came with the sight.
As I said it works for me .
