There is a single steel bead sight on the heat shield, the barrel is choked cylinder and has a 2 3/4 inch chamber. The barrel has the standard markings. Mounted on a round walnut forearm with 18 grooves. The smooth walnut pistol grip stock has a checkered plastic buttplate with the length of pull being 14 inches.
