When your front sight sits too low to line up with the rear, this Marble Arms dovetail ramp is the fix. Machined from solid steel and finished in black, it raises your sight blade to the height you need without throwing off the look of your barrel. It's cut for a .6875" barrel radius with a low .095" profile, and the 3/8" dovetail on top accepts a wide range of bead and fiber optic front sight blades, so you can build the exact sight picture your rifle and load call for.
Marble Arms has been making iron sights for around a century, and this ramp carries that same no-nonsense reputation. The .095" sight height (measured from the bottom of the radius to the bottom of the dovetail) is the lower of the two heights Marble offers in this line, making it a good match when you only need a modest bump to get your front and rear sights talking. Because the dovetail is a standard 3/8", you're not locked into one blade. Gold bead, ivory bead, or a glowing orange or green fiber optic rod all drop right in.
Installation is straightforward but deliberate. The ramp attaches to the barrel with a single 6-48 screw seated under the sight body, and many builders solder it in place for a permanent, rock-solid hold. That radius base is machined to hug a .6875" contour barrel, so it maintains the shape of the barrel rather than sitting on top like an afterthought. Getting the exact height right takes a little math between your sighting radius and rear sight range, and most folks let a gunsmith handle the fitting to keep everything true.
Whether you're restoring an older rifle or setting up a custom build, this ramp gives you a clean, dependable foundation for a front sight that actually lines up where it should.
The ramp uses a standard 3/8" dovetail, so it accepts a wide range of Marble Arms dovetail front sights. That includes gold bead, ivory bead, and orange or green fiber optic blades. You pick the blade height and style that gives you the sight picture your rifle needs.
Marble measures ramp height from the bottom of the radius to the bottom of the dovetail slot. At .095", this is the lower of the two heights offered in this ramp line. It's the right pick when you need only a small increase to bring your front sight in line with the rear.
The ramp mounts with a single 6-48 screw that seats under the sight body, and the screw is included. Many builders also solder the ramp for a permanent hold. Because installation involves drilling and fitting, most people have a gunsmith do the work to keep everything aligned.
This version is cut for a .6875" barrel radius, so the curved base matches that contour and follows the shape of the barrel. Measure your barrel diameter at the muzzle end before ordering, since Marble offers this ramp in several contours. Getting the contour right is what makes the ramp sit flush instead of rocking.
