Marble Arms .500-inch Barrel-Mounted Front Sight, Brass Gold

The Marble Arms .500-inch Barrel-Mounted Front Sight in brass gold (Marble Arms part no. 205031) is built for lever-action and bolt-action rifle owners who need a taller replacement bead than the standard .410 or .450-inch heights. Marble Arms has supplied American sporting rifles with front and rear sights since the early 1900s, and this 50-W pattern bead keeps that same barrel-mounted, no-gunsmithing design. It attaches straight to the barrel post rather than a dovetail slot, so it installs with basic hand tools. The brass gold bead offers a warm, high-visibility sight picture that shows up quickly against a dark rear notch.

Key Specifications

• The bead stands .500 inches tall, a taller option for barrels needing more elevation than the .410 or .450-inch beads.
• A 3/32-inch blade width keeps the sight narrow enough for precise open-sight aiming.
• The barrel-mounted design attaches directly to the barrel post, so no dovetail cutting is needed.
• Its brass body resists corrosion better than a bare steel bead over years of field use.
• The gold finish gives a warm, easy-to-see sight picture in variable field light.

Frequently Asked Questions

How do I know if I need the .500-inch height instead of a shorter bead? The .500-inch height is meant for barrels sitting lower relative to the rear sight and needing more front sight elevation than the .410 or .450-inch beads provide; compare against your current bead height before ordering.

Does this sight need a dovetail cut in the barrel? No, it is barrel-mounted and attaches directly to the barrel post rather than requiring a dovetail slot.
