Marble Arms .450'' Fiber Optic Glow 45-W Front Sight Steel Green
$20.18
The Marble Arms .450" Fiber Optic Glow 45-W front sight in steel green is a ramp-mounted front sight designed for rifles that need a rugged, visible aiming point in varied light conditions. This is a straightforward upgrade from factory irons or a reliable backup to your primary optic—the kind of sight that earns its place on a hunting rifle or precision .45-70 lever gun through simplicity and glow-in-the-dark performance. The gracefully contoured steel blade slopes toward the front for a clean profile, and the nickel-steel construction wears a traditional blue finish that suits working guns.
What sets glow sights apart is their fiber optic rod. This one uses a .060" diameter green-glowing rod that collects available light during the day and emits a soft glow in low-light hunting conditions—dawn, dusk, or thick timber. You're not dependent on batteries or active illumination; the sight gathers ambient light and radiates it when you need to pick up your sight picture fast. The .340" wide ramp-mounted base fits rifles designed for ramp-style front sight installation, a common feature on classic lever actions and some bolt rifles.
This is the kind of sight that appeals to hunters who trust proven mechanics and want their iron sights to be genuinely visible without fuss. Whether you're running it as a primary aiming system on an open-country rifle or keeping it as a mechanical backup on a scoped gun, the Marble Arms glow sight has earned respect among hunters for decades. It's not flashy, but it works when you need it most.

Frequently Asked Questions
What rifles use a .340" wide ramp-mounted front sight?
Ramp-mounted front sights are commonly found on lever-action rifles and some traditional bolt-action designs. Check your rifle's existing sight base to confirm compatibility before ordering. If you're unsure, contact us with your rifle model and we can help you verify fit.
How does the green fiber optic glow work without batteries?
The .060" diameter fiber optic rod is a light-gathering material. During the day or in any ambient light, the rod absorbs and transmits that light. In low-light conditions like dawn, dusk, or overcast hunting scenarios, the accumulated light within the rod becomes visible as a soft glow at the sight picture, making it easier to find your aiming point quickly without an external power source.
Is this sight suitable for hunting?
Yes. The Marble Arms glow sight is designed for rifles used in hunting and sport shooting. It works as a primary sight on open-sighted rifles or as a reliable mechanical backup to a scoped rifle. The glow technology is especially useful during low-light hunting hours when other irons can fade.
What's the blade height on this sight?
The front blade is .450" tall. This measurement helps you verify proper sight picture alignment with your rear sight, especially if you're replacing an existing front sight or setting up open iron sights on your rifle.
