Marble Arms .500'' Barrel Mounted 1/16'' 50-W Front Sight Steel White
$16.46
The Marble Arms .500'' Barrel Mounted Front Sight in white offers a classic, proven sighting solution for rifles with barrel-dovetail cuts. This steel barrel-mounted front sight features a 1/16'' white polymer bead—a traditional choice favored by shooters who prefer high-visibility, low-maintenance aiming points on hunting rifles, competition guns, and vintage builds. The gracefully contoured blade slopes naturally toward the front, and the rounded base sides fit seamlessly into dovetail cuts made directly in the barrel, making installation straightforward on compatible rifles.
Marble Arms has been making precision sights for generations, and this front sight carries that heritage. The steel construction is built to last, and the white polymer bead provides excellent contrast in varied light conditions—it won't chip like ivory, and it won't require touch-ups the way paint or lacquer might. The 17/32'' wide base ensures solid purchase in the dovetail without excess material that could interfere with your sight picture or handling.
Whether you're restoring a classic rifle, setting up a plains rifle, or prefer the simplicity and durability of open sights over optics, this Marble Arms front sight delivers reliable, no-battery performance. Pair it with a compatible rear sight to build a lightweight, efficient aiming system.

Frequently Asked Questions
Will this front sight fit my rifle?
This is a barrel-mounted sight designed for rifles with a dovetail cut directly into the barrel at the front. If your rifle's front sight is soldered or pinned on, or if it uses a ramp base, this sight will not fit. Verify your barrel's dovetail specifications and that the 17/32'' base width matches your rifle's cut.
What's included?
You receive the front sight assembly with the white polymer bead and steel base. You'll need a compatible rear sight to complete an open-sight system. Installation typically requires a dovetail pusher or gunsmith services.
Why choose white polymer over other bead options?
The white polymer bead provides excellent visibility in most lighting conditions and is more durable than painted or lacquered finishes. Unlike ivory or soft materials, it resists chipping and doesn't require regular maintenance to maintain its appearance.
Is this sight adjustable?
No—this is a fixed front sight. Elevation and windage adjustments are made through your rear sight.
