On my JP Sauer mauser sporter, the one I just got a Lyman 35 rear sight for, I need to replace the front sight with a higher one to work well with the Lyman. After shooting it some and figuring out how off it is, I find I need a sight taller than the one on it by about .180". So a total height of about 1/2".
It is the narrow style dovetail sight with the rounded base at the rear that pushes in from the front. Not side to side dovetail like most modern sights. Width at the base is .190" and it is .90" long.
Looks like this:
https://www.gunpartscorp.com/ad/1287470.htmNECG offers many sights that are of this style, but none that are tall enough and I cannot find anybody else that seems to offer that type of sight. I will make one of I have to, but figured I would ask if anyone out there knows of anyone selling them or offering blanks that can be shaped down.
