Dove-tail groove dimensions

[Doug444]

I'm working on designing a simple (read inexpensive) peep site that can be slipped into the gooved receiver on most .22's and use the original front sight. Anyone know where I can get the standard dimensions for the grooves on these receivers? I've measured them on what I have (Marlin bolt and semi-autos) and there seems to be some significant variation. Any help would be appreciated.

Doug, they will vary from maker to maker. I'd put some sort of adjustment in the "clamp" of the sight. Maybe even fore and aft set screws. George

I have a Star Super B that I conveted to 9x23.
I would like to get an adjustable rear sight.
It looks like a 1911 and the sight dovetail looks like .330" wide, .3" high, and 60 degrees, but it could be .345" wide or 65 degrees. How does one tell before they odrer a sight?
