Marble Arms .450in Barrel-Mounted Front Sight, 3/32in Thread, Brass White

The Marble Arms .450in Barrel-Mounted Front Sight, 3/32in Thread, Brass White is a replacement front sight from Marble Arms (brand part no. 204532) sized to a .450-inch sight height. It uses a base that threads directly into a barrel-mounted dovetail or screw hole, 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 white 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.
