Marble Arms .410'' Fiber Optic Glow 41-W Front Sight Steel Green
The Marble Arms .410" Fiber Optic Glow 41-W front sight brings bright, low-light visibility to rifles without sacrificing classic aesthetics. This steel front sight features a green fiber optic glow rod that catches available light and maintains visibility in dim conditions—ideal for hunters working dawn and dusk, or shooters on overcast ranges. The gracefully contoured blade slopes toward the front for a refined profile, and the nickel-steel construction blends seamlessly with traditional rifle finishes.
Built for ramp-mounted applications, the 41-W installs on rifles equipped with standard ramp bases, making it a straightforward upgrade for classic and modern sporting rifles alike. The .060" diameter fiber optic rod is the business end here—that thin green core is what glows, catching even modest ambient light to keep your front sight picture sharp and fast when conditions get sketchy.
Whether you're upgrading aging iron sights or adding a reliable auxiliary sight to a scoped rifle, this Marble Arms front sight delivers rugged, no-nonsense performance. The green glow is particularly effective in low-light hunting scenarios, and the steel construction means it'll hold zero and withstand field use.
