Marble Arms .450-inch Barrel-Mounted Front Sight, Brass Gold

The Marble Arms .450-inch Barrel-Mounted Front Sight in brass gold (Marble Arms part no. 204531) replaces a worn or missing front bead on a classic lever-action or bolt-action rifle barrel. Marble Arms has built sporting rifle sights since the early 1900s and is still the standard reference for drop-in barrel sights that need no gunsmithing. This 45-W pattern bead attaches directly to the barrel post instead of requiring a dovetail cut, so a hunter or collector can swap it on with basic tools. The brass gold face gives a warm, high-visibility bead that stands out clearly against a dark rear sight notch.

Key Specifications

• The bead stands .450 inches tall, a common replacement height for older lever-action barrels.
• A 3/32-inch blade width keeps the front sight narrow enough for precise open-sight alignment.
• The barrel-mounted design attaches directly to the barrel post, eliminating the need for a dovetail cut.
• Its brass body is naturally corrosion-resistant and won’t rust the way a bare steel bead can.
• The gold face color gives a warm, fast-acquiring sight picture in both bright and low light.

Frequently Asked Questions

Does this sight require a dovetail cut in my barrel? No, it is a barrel-mounted design that attaches directly to the barrel post, so no dovetail slot needs to be cut.

Why choose brass gold over the steel white version? Brass gold gives a warmer, high-visibility bead and natural corrosion resistance, while steel white offers a brighter, cooler-toned sight picture; both share the same .450-inch height and 3/32-inch blade width.
