Description

Marble Arms has been a name in gun sights since 1892, and this 50-W front sight carries that same no-nonsense reputation. It stands .500" tall with a .531" wide base and a 1/16" gold bead, making it a popular replacement or upgrade for vintage and modern rifles alike. The gold bead catches light well, giving your eye a quick reference against dark game or paper targets without washing out in bright conditions.

How the 50-W Front Sight Mounts Up

This is a barrel mounted sight, meaning it's built for guns that have the front sight dovetail cut directly into the barrel rather than sitting on a ramp. The base sides are rounded to match that style of installation, and it fits a common 3/8" dovetail. Installation is a drift-in job using a brass or nylon punch, tapped in from the side. Some barrels run a touch tight, so a little careful fitting may be needed to get a clean, snug seat.

Why Shooters Keep Reaching for Marble Arms Sights

Marble Arms has been outfitting rifles from Winchester, Marlin, Savage, and Remington for well over a century, and that heritage shows in the fit and finish. The blade carries Marble's signature contour, sloping gracefully toward the front for a clean sight picture. The .500" height makes it a strong match when you're pairing it with a rear semi-buckhorn and need a little more elevation to dial things in.

If you're restoring an old lever gun that's missing its front bead or just want a brighter aiming point than a plain post, this 50-W gives you a proven, American-made option that's served hunters and target folks for generations. Measure your dovetail width and desired height before ordering so you land on the right fit the first time.

Frequently Asked Questions

What kind of rifle does the Marble Arms 50-W front sight fit?

This sight is designed for rifles with a standard 3/8" dovetail cut directly into the barrel. It's a universal-fit style that's commonly used on lever guns and vintage rifles from makers like Winchester, Marlin, and Savage. Measure your dovetail width and the height you need before ordering to be sure it's the right match.

How do I install the 50-W barrel mounted front sight?

It drifts into the dovetail from the side using a brass or nylon punch, which protects the finish and the bead. Windage is adjusted the same way, by gently tapping the sight left or right in the slot. If your barrel's dovetail runs tight, a little light fitting may be needed to seat it cleanly.

What's the difference between a barrel mounted and a ramp mounted Marble Arms sight?

A barrel mounted sight like this 50-W has rounded base sides and is built for dovetails cut straight into the barrel. Ramp mounted sights have straight-sided bases designed to sit on a front sight ramp instead. Picking the correct style matters, so match it to how your rifle's front sight area is set up.

Why choose a gold bead over a white one?

The gold bead on this sight tends to stand out well against dark targets and game, and it holds up nicely in bright light without glaring back at you. Marble Arms also offers this same 50-W in an ivory white polymer bead if you prefer that contrast. It comes down to which color your eye picks up fastest in your shooting conditions.
