Marble Arms .450'' Fiber Optic Glow 45-Mr Front Sight Steel Green

The Marble Arms .450" Fiber Optic Glow front sight in steel green gives you a bright, glowing aiming point that cuts through low-light hunting conditions and ranges. Built with traditional craftsmanship, this ramp-mounted front sight pairs rugged steel construction with a gracefully contoured blade that slopes naturally toward the front—a classic profile that complements classic rifles. The green fiber optic rod (.060" diameter) glows under ambient light and catches fast in shadowy timber or dawn and dusk hunting windows, letting you acquire your target faster than plain metal blades.

Marble Arms has been making quality iron sights since before red dots and magnified optics became standard, and this sight proves why hunters and shooters still trust them. The .450" height and .340" base width fit ramp-mounted rifle systems where precision alignment matters. Whether you're running iron sights as a primary or backup to a scope, this front sight delivers the visibility and durability you need in the field.

If you hunt or shoot in mixed light—early morning stands, thick cover, or overcast days—a glowing fiber optic front sight keeps you fast and accurate without batteries or electronics. Pair it with a matching Marble Arms rear sight for a complete, reliable sighting system that works every time you shoulder your rifle.

Frequently Asked Questions

Will this front sight work with my rifle's ramp base?

Yes, this Marble Arms sight is designed for ramp-mounted rifles with standard dovetails. The .340" base width and .450" height are typical dimensions for classic rifle setups. Check your rifle's dovetail width and front sight height requirements before ordering.

How does the green glow fiber optic work without batteries?

The green fiber optic rod absorbs and reflects ambient light (sunlight, overcast, artificial light) to create a glowing aiming point. No batteries, electronics, or activation needed—it glows whenever there's enough light to see by, making it ideal for dawn, dusk, and timber hunting.

What rear sight should I pair with this front sight?

For a complete iron sight system, match this front sight with a Marble Arms rear sight designed for the same rifle platform. Both sights should be compatible with your rifle's dovetail spacing and height requirements.

Is this sight durable for hard hunting and rough handling?

Marble Arms sights are made from blued steel and built to traditional standards for reliability and longevity. They're designed to withstand the demands of field hunting and shooting sports without requiring optic batteries or electronic maintenance.
