That's not a bad price, including the front sight. The OEM for Browning regularly sells the rear sight on ebay for about $300. Don't think that price includes the front sight, but I could be wrong. The caution on this deal is that the Shiloh Sharps front dovetail that this sight is made for is pretty unique, 7/16", and most purchasers or owners of a Shiloh would probably go for better sights. The tang sight should fit a Pedersoli Sharps too, but the Pedersoli front dovetail is 3/8", so this sight package is a bit of an odd combo.
