Marble Arms Rifle Dovetail Front Ramp .625'' Id .375'' Black

The Marble Arms Rifle Dovetail Front Ramp in .625" ID and .375" height is a solid steel front sight base built for gunsmiths and shooters who want to upgrade or repair iron sights on rifles. This dovetail ramp accepts Marble Arms fiber optic, ivory, and brass bead sight blades, giving you flexibility to choose your preferred sight style—whether you're building a custom rifle, restoring a vintage gun, or replacing a damaged front sight. The ramp is engineered to fit a variety of barrel profiles across current and older production rifles, making it a practical solution for both classic and modern firearms.

Installation is straightforward: the ramp mounts to your barrel with a single screw seated under the sight body, plus solder for permanent attachment. The flat base is pre-drilled for two additional mounting screws, so you have solid, redundant fastening. The black finish resists corrosion and blends with most rifle builds. This is a quality component made by Marble Arms, a maker respected for iron sights and sight systems across generations of American rifles.

If you're a gunsmith, a builder, or someone who prefers the reliability and simplicity of iron sights, this dovetail ramp is a durable foundation for a front sight setup that will outlast trends.
