Marble Arms .500in Ramp-Mounted Front Sight, 1/16in Thread, Brass Gold

The Marble Arms .500in Ramp-Mounted Front Sight, 1/16in Thread, Brass Gold is a replacement front sight from Marble Arms (brand part no. 505021) sized to a .500-inch sight height. It uses a base that sits on a barrel’s factory sight ramp for a solid, low-profile mount, keeping the classic Marble Arms sight profile that generations of rifle owners have used to replace worn or damaged factory sights. Built in brass with a gold finish, it is a drop-in upgrade for gunsmiths and rifle owners restoring or customizing a barrel’s factory sight setup. This is sold as an individual front sight, not a complete sight set.
