I have an old rifle with a pinned on front sight ramp. The dovetail in the ramp is 1/4" instead of the normal 3/8" (I'm talking about the front-to-back measurement). Does anyone know of a source of these sights?
The British enfield rifles use a blade that I think is about 1/4", but I haven't measured one to know for sure. They are only about 1/4" to 5/16" high though. If you have a mill it's not that hard to make what you need.
