The Marble Arms .343-Inch Ramp-Mounted Front Sight in brass gold (Marble Arms part no. 503421, model 34-MR) is built to attach to an existing ramp base rather than mount directly to the barrel, unlike the barrel-mounted version in Marble Arms’ lineup. The .343-inch base diameter and 1/16-inch blade width match specific factory ramp dimensions, and the brass gold finish gives a bright, easily visible sight picture, a traditional look associated with classic lever-action and sporting rifles. It’s a direct-fit replacement for shooters restoring a ramp-mounted iron sight setup.

Frequently Asked Questions

What’s the difference between this and the barrel-mounted version? This sight attaches to an existing ramp base rather than mounting directly onto the barrel, so the correct choice depends on which style your rifle already uses.

How do I know if this fits my rifle’s ramp? Matching the .343-inch base diameter against your existing ramp, or checking with our staff, is the safest way to confirm fitment.

What does the brass gold finish add? It gives a brighter, more visible sight picture than a plain blued or black blade.
