It features a brass bead front sight and a receiver groove rear sight, a 2 7/8 inch chamber and is mounted with smooth walnut forearm panels and a round knob pistol grip stock with the less common checkered steel buttplate. It has sling swivels on the magazine tube and bottom of the butt. The length of pull is 13 1/8 inches.
