Marble Arms .500'' Barrel Mounted 1/16'' 50-W Front Sight Brass Gold

The Marble Arms .500'' barrel mounted front sight with 1/16'' 50-W brass gold bead is a traditional, classically-styled front sight for rifles with a barrel dovetail cut. This is a no-frills choice for shooters building or restoring a rifle with period-correct or working-grade sights. The contoured blade design slopes gracefully toward the front, and the rounded base sides fit snugly into standard barrel dovetails. Steel construction with blued finish integrates cleanly on most rifle platforms, while the brass gold bead—polished to catch light naturally—provides a visible aiming point without batteries, coatings, or electronics to fail.

Marble Arms has made sights for generations, and their barrel-mounted designs remain popular among hunters, precision shooters, and enthusiasts who prefer simple iron sights or who are fitting a rifle with original-style front sight hardware. The 17/32'' wide base is standard for W-pattern sights, and the 1/16'' bead diameter offers a fine sight picture suitable for both hunting and target work. This is honest, proven sight hardware—not a modern tactical accessory, but a reliable option for anyone who trusts iron sights and wants to avoid the bulk of mounted optics.

Installation requires a barrel dovetail cut and some gunsmithing knowledge or professional fitting. If your rifle already has the dovetail machined, this sight drops in place and requires basic attention to proper seating and alignment. Check your rifle's barrel dimensions and dovetail specifications before ordering to ensure compatibility.

Specifications

Frequently Asked Questions

Will this front sight fit my rifle?

This sight is designed for rifles with a barrel dovetail cut. Your rifle must have a dovetail machined directly into the barrel at the front to accept this sight. Check your rifle's specifications and barrel dimensions (including the .500'' dovetail) before ordering. If you're unsure, consult your rifle's manual or a gunsmith.

What's the difference between this bead and other Marble Arms options?

Marble Arms offers barrel-mounted front sights in several bead styles: this brass gold finish, ivory (white polymer), and variations in diameter. The 1/16'' brass gold bead is a fine, visible aiming point that catches ambient light naturally—a classic choice for hunting and target shooting.

Do I need a gunsmith to install this sight?

Installation requires your rifle to already have the dovetail cut. If the dovetail exists, the sight should seat with hand pressure or light tapping and a drift punch. Proper alignment is critical, so professional fitting is recommended unless you have experience with sight installation and your rifle's specific geometry.

What's included?

You receive the front sight itself. Installation hardware, shims, or detailed fitment tools are not included. Your rifle must be properly set up to accept barrel-mounted dovetail sights.
