Marble Arms .343'' Fiber Optic Glow 34-Mr Front Sight Steel Orange
$20.18
The Marble Arms .343'' Fiber Optic Glow front sight in orange is a ramp-mounted, steel rifle sight built for shooters who need reliable acquisition in variable light. Unlike generic blade sights, this Marble Arms front sight combines traditional steel construction with modern fiber optic technology—a .060" diameter glow rod that collects ambient light to create a bright aiming point without batteries or electronics. It's a straightforward upgrade for hunters and marksmen running iron sights or irons-primary setups on rifles equipped with ramp bases.
The sight's tapered blade design slopes toward the front, reducing glare and offering a clean sight picture across hunting distances and shorter-range precision shooting. The orange fiber optic element excels in low-light conditions—dawn woods, dusk fields, or overcast game drives—where standard steel sights fade but artificial illumination isn't practical or allowed. Steel construction means it'll outlast the rifle if treated fairly, and the blued finish integrates naturally with most rifle builds.
Ramp mounting keeps installation and removal straightforward on guns designed for that base system. The .340-inch base width is proportioned for standard ramp systems. This is an honest sight for hunters and shooters who prefer irons, want zero batteries or complicated electronics, and appreciate Marble Arms' reputation for simple, durable optics that work year after year.

Frequently Asked Questions
Will this front sight fit my rifle?
This sight is ramp-mounted with a .340" base width, so it's designed for rifles equipped with standard ramp base systems. Check your rifle's front sight mounting system before ordering; not all rifles use ramp bases.
How bright is the orange fiber optic in low light?
The .060" diameter fiber optic rod gathers available ambient light and glows orange without batteries. Performance depends on available light—it works best at dawn, dusk, or overcast conditions where enough light reaches the rod. In complete darkness, it will not glow.
Can I use this with a rear iron sight or scope?
Yes. The front sight can be paired with compatible rear iron sights. If you plan to mount a scope, verify that your rifle's sight base system doesn't interfere with your scope mounting solution.
What finish does this sight have?
The sight is blued steel, offering traditional aesthetics and corrosion resistance typical of quality rifle irons.
