Marble Arms .410'' Fiber Optic Glow 41-Mr Front Sight Steel Orange
The Marble Arms .410" Fiber Optic Glow 41-Mr front sight brings bright, fast target acquisition to rifles equipped with ramp bases. This steel sight uses an orange fiber optic rod to gather and amplify available light, making it visible in low-light hunting and shooting conditions without batteries or electronics. The gently contoured blade slopes toward the front for a clean sight picture and professional appearance on your rifle.
Marble Arms has built a reputation for rugged, reliable iron sights, and this model delivers precision engineering in a compact package. The .340" wide base mounts solidly to standard ramp bases, and the graceful blade design won't snag on gear or clothing. Whether you're setting up a backup sight system, upgrading aging factory iron sights, or building a truck gun that doesn't rely on glass, this front sight offers dependable performance at the range or in the field.
The orange fiber optic rod is the key to this sight's utility. Unlike traditional blued steel sights that fade in shadow or overcast conditions, the bright rod collects ambient light and glows consistently across shooting conditions. It's a simple, effective upgrade for hunters and shooters who want faster target location without adding weight or complexity to their rifle.
