The Henderson Precision Hunter 1.5 Dovetail Arca Swiss rail was designed to be extremely light (1oz) and low pro. It is Arca Swiss compatible and 3 inches in length. It's designed with a center mounting slot to fit a wide variety of stock applications. The Hunter rail is very low and sleek and idea for that next Ultra-light rifle. The Hunter rail is supplied with 1-inch button head 10/32 screws and t-nuts. It will work with Arca Swiss quick release or thumb screw clamps. All rails are bead blasted mil-spec type III hard anodized.
