Cookiemann,
I will try to post a picture. I am not good at this kind of thing but I hope my wife can help me. I'll try to do it this weekend. Thank you for your patience.
Meanwhile, I think you may be able to easily recreate what I did:
The standard tracker barrel rear sight apparently comes in three pieces. It consists of an anchor piece, which is sodered to the barrel. Above this is a movable elevation ramp, with a screw to tighten it where you want it.
This is topped by a U-notch (like a V-notch, or buckhorn sight). Mine was missing when they sent me the new barrel, so I fastened a bolt on the elevation ramp, temporarily, with duct tape.
Basically, I made a peep sight for the cost of a small bolt.
This seems to be a very forgiving arrangement, at least with the Remington copper solids that I used at the range. At 15 yards with 6 oclock hold a scored a centered bulls eye. This set up rocks!
