Marble’s® has developed a line of uni-ramp front sights that fit all rifles, shotguns, and muzzleloaders that use screw held front sights. The brilliantly glowing fiber optic cables are installed and permanently flared to the sight. Both ends of the optic cable are carefully polished to enhance light transmission and are uniquely protected from UV damage due to long term exposure to sunlight. Each one is precision CNC machined from solid steel to our exacting standards. These fine sights are machined, polished, and blued to match your gun. The Marble’s® uni-ramp front sight is available in fluorescent orange and green in a variety of heights. >>Uni-Ramp Front Sight Specifications
