I removed the rear sight on my Thompson 1928 model and I would LOVE to find a rail for it.
These are the dimensions, as you can see there's a hole further back almost 3 inches. I found one with sliding screws for adjustments but it was 5 inches or so, and wouldn't fit.
If anyone could help me find any type of rail system that could attach to that setup in any way i'd be very grateful. I've looked for hours and can't find anything.
