This Marble's manufactured automatic flexible joint tang peep sight is for the Remington model 8 and 81 semi-auto rifles and is in very good condition retaining most of its original blue finish turning a brown patina with light wear. The mounting screw is not included but is sold seperately. A great peep sight for your collectible Remington rifle.  (file photos)
