This small version is made for a longrifle with a slim 13/16" or 7/8" octagon barrel. Wax cast steel, this sight has a long base similar our other Pennsylvania sight #RS-FG-14. However this sight is .425" tall from the top of the sighting surface, to allow sight-in with a tall front sight, and to reduce mirage and heat glare from the top flat, during shooting matches. A .755" dovetail is about .540" wide. Dovetail to a depth of .050", or fit to a raised dovetail.
