Marble Arms .410in 41-W Fiber Optic Front Sight, Steel Green

The Marble Arms .410in 41-W Fiber Optic Front Sight, Steel Green is a replacement front sight from Marble Arms (brand part no. 204136) sized to a .410-inch sight height. It uses a green-glow fiber optic insert that gathers ambient light for a bright, fast sight picture in low light, keeping the classic Marble Arms sight profile that generations of rifle owners have used to replace worn or damaged factory sights. Built in steel with a green 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.
