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 or green inserts. Front sight can also be used with GSG Novak’s plain, wide-notch rear. GSG 1911 front sights are the same height as factory sights and fit factory dovetails; no machining required.
