Marble Arms .450'' Barrel Mounted 1/16'' 45-W Front Sight Brass Gold

The Marble Arms .450" Barrel Mounted 1/16" 45-W Front Sight in Brass Gold is a classic aftermarket front sight designed for rifles with dovetail cuts machined directly into the barrel. Built from blued steel with a gracefully contoured blade that slopes toward the front, this sight delivers the clean lines and durability that have made Marble Arms a trusted name among riflemen, gunsmiths, and vintage gun enthusiasts for over a century. The 1/16" brass gold bead provides excellent visibility in a wide range of lighting conditions, making this sight a natural choice for hunting rifles, vintage military builds, and classic sporting firearms.

The "W" designation indicates a 17/32" (13.5mm) wide base, sized to fit the standard dovetail cut found on many rifle barrels. The rounded base sides mate smoothly with barrel-mounted dovetails, ensuring a solid, repeatable fit. The bead itself—small, bright, and precisely machined—sits at eye level when the sight is properly mounted, allowing you to acquire targets quickly without the bulk or complexity of modern optics. This is the kind of sight that works just as well on a .22 rimfire as it does on a centerfire hunting rifle.

Whether you're restoring a vintage rifle, replacing a lost or damaged original sight, or building a rifle the way they were intended, Marble Arms front sights are engineered to last. The blued steel finish resists corrosion and develops character over time. Unlike polymer or plastic alternatives, this brass gold bead won't fade or yellow with UV exposure, keeping its warm, visible tone year after year in the field.

Frequently Asked Questions

Will this sight fit my rifle's barrel?

The Marble Arms 45-W is designed for rifles with a dovetail cut machined directly into the barrel. The 17/32" wide base is a standard dimension. Measure your existing dovetail or check your rifle's manual to confirm compatibility before ordering.

What's the difference between brass gold, ivory, and other bead options?

Marble Arms offers this sight with a 1/16" brass gold bead, which provides a warm, reflective appearance and excellent visibility across daylight conditions. Ivory (white polymer) beads are also available in 1/16" diameter on other models if you prefer a different look or visibility profile.

Is this sight suitable for hunting or target shooting?

Yes. The small, bright brass gold bead works well for both hunting and range use on rifles where barrel-mounted open sights are appropriate. It's especially popular on classic rifles, vintage military builds, and firearms where traditional sighting is preferred over modern optics.

Does this sight require any tools or gunsmithing to install?

Installation requires that your rifle already have a dovetail cut in the barrel. Assuming the dovetail is the correct size and depth, the sight should slide into place and secure with a dovetail key or set screw (typically included with your rifle or available separately). If you're unsure, consult a gunsmith.
