Marble Arms .500-inch Barrel-Mounted Front Sight, Steel White

The Marble Arms .500-inch Barrel-Mounted Front Sight in steel white (Marble Arms part no. 205032) gives lever-action and bolt-action rifle owners a taller replacement bead in a hard-wearing steel body. Marble Arms has built American sporting rifle sights since the early 1900s, and this 50-W pattern keeps the brand’s signature barrel-mounted, no-gunsmithing installation. It attaches directly to the barrel post instead of a dovetail slot, so it swaps on with basic hand tools. The white face finish delivers a bright, high-contrast sight picture that’s easy to pick up quickly in the field.

Key Specifications

• The bead stands .500 inches tall, a taller option for barrels needing more front sight elevation.
• A 3/32-inch blade width keeps the sight narrow enough for precise open-sight alignment.
• The barrel-mounted design attaches directly to the barrel post, so no dovetail cutting is required.
• Its steel construction holds up to recoil and field use better than a cast alternative.
• The white face gives a bright, fast sight picture against darker rear sights.
