this is a Paul Jaeger scope mount I got on Ebay for the sporster I have been putting together ... It has a base that attaches to the receiver and a scope mount and rings that slides onto the base well have a look

Sporster, I had one of those back in the day. I traded it for my first production lathe back in 1983. Put 25,000 miles on it before I traded it off.  1973 XLCH kick start Harley Sporster. Was wondering why anyone would put a scope on one. Insert smiley here.

Nice looking sporter in the photo. So now it makes sense.
