No it didn't, It's raised but not a dovetail (straight cut), won't work with this peep sight. I thought about a flat plate & add a piece of dovetail stock... or try to find just the mounting bracket with side mounting screw only, the upper sight appears to be the same?... Seems to be a Redfield #70 and a #75, don't know the difference yet. I'm wondering if the Winchester 52's or other 22's used a flat plate? Thanks again, Mike
