Thompson factory forend screw washers for all standard rifle and pistol forends. Sold in "pairs" only.
NOTE: If you think your original factory washers are missing because they don't come out of the forend with the screws check the inside of the screw holes in the forend before ordering replacement washers. Many times the washers become lodged in the forend screw hole and they won't come out when the screw is removed. A thin punch must be inserted in the screw hole from the top side and tapped with a small hammer to dislodge them. Make certain that your washers are not lodged in the forend before ordering additional washers. If you inadvertently install two washers on the screw(s) they will then be too short to attach the forend too the barrel in the proper fashion.
