Marble’s® has been making folding rear sights for 94 years. They flatten on top of a gun barrel to allow the use of a Tang Peep sight or scope without inference. Our Folding Leaf Rear Sight is available as windage adjustable or drift adjustable. This unique feature allows you to precision adjust your sight with a small screwdriver or a hammer. The height adjustable notch piece has both U-shaped and V-shaped centers. You can remove and reverse your notch piece with a small screwdriver. The hand painted enamel diamond draws the eye to the center of the notch for lightening quick sight alignment. Marble’s® Folding Leaf Rear Sights are machined from solid steel and are available in traditional flat-top style. We make these fine sights in four heights from .347 inches to .557 inches. Notch Piece Our unique reversible notch piece gives you a choice of "U" or "V" shaped notch. A hand painted white enamel diamond helps draw your eye to the center of your notch. Held in place by sight screw. Can be adjusted vertically for height. >>Folding Leaf Sight Specifications
