Advanced light gathering properties of fiber optic rods make maximum use of ambient light to provide a bright glow that stands out against dark backgrounds and puts you on target fast, even in low-light or high-stress situations. Fronts and rears sold separately, so you can create a custom, three-dot, fiber optic system tailored to your shooting needs. Available with red inserts. Front sight can also be used with Novak's plain, wide-notch rear. Mfg: Novak
