I saw the same thing but this doesn't appear to be the same rear sight as in the drawing. Mine has a separate screw that will loosen the leaf to adjust for windage where others seemed to use a drift fit.brewster7 said:Welcome from Central Texas.
You pose an interesting question about your 795. I went to Marlin's customer service and looked up the owner's manual for the 795:

The illustrated parts breakdown in the back of the owner's manual doesn't show a screw for the rear sight.
Good luck.
