Marble Arms Rifle Dovetail Front Ramp .875'' Barrel Od .100''Height/Black

The Marble Arms Rifle Dovetail Front Ramp is a classic steel front sight ramp designed to upgrade or repair iron sights on rifles with dovetail mounting systems. This .875" barrel OD ramp stands .100" tall and fits the mounting footprint of a wide range of rifle builds—everything from vintage Winchesters to modern custom projects. Built from solid steel and finished in black, it provides a reliable foundation for fiber optic, ivory, or brass bead sight blades, letting you choose the sight picture that works best for your shooting style and conditions.

Marble Arms has been making quality iron sight components for generations, and this ramp carries that heritage. The design is straightforward and proven: it attaches to your barrel with a single screw beneath the sight body, plus solder for permanent security. The flat base is drilled for two mounting screws, giving you multiple mounting options depending on your rifle's existing setup. If you're restoring an older rifle or building a custom hunting or sport rifle without factory sights, this ramp gets you back in the game with minimal gunsmithing.

Whether you're working on a .30-30, .308, or any rifle in that barrel contour range, this Marble Arms ramp is the kind of no-nonsense component that serious rifle builders and restoration shooters reach for. It's not flashy—it's just solid steel that does what it's supposed to do, year after year.
