Marble Arms has been making iron sights since 1900, and the 41-MR fiber optic front sight is a great example of why folks keep coming back. This one measures .410" in height with a .531" barrel-mounted width, so it slots into a standard 3/8" dovetail. The green fiber optic tube gathers ambient light and glows, giving you a crisp aiming point that stands out against dark game, timber, and low-light conditions where a plain brass or ivory bead tends to disappear.
Every one of these sights is CNC machined from solid steel, then polished and blued to match the look of your gun. The fiber optic cable is permanently flared into place at both ends and the tips are polished to pull in as much light as possible. Marble also treats the optic to resist UV damage, so it holds up to years of sun exposure without going dull. That combination of a glowing dot and honest-to-goodness steel construction is the whole appeal here. You get the visibility of a modern fiber optic with the toughness of an old-school iron sight.
The .410" height is the starting point Marble uses in their own sight-correction charts, so it's a popular pick for lever guns and other classic rifles running a rear peep or open sight. Like most dovetail sights, it may need a little fitting with a fine file to seat tight, which is normal and gives you a rock-solid hold once it's in. A brass punch and a light hammer tap does the rest. Folks with aging eyes especially tend to love the upgrade over a traditional bead.
If your rifle takes a .410" front sight and you want quicker target acquisition without giving up that traditional profile, this green fiber optic 41-MR is a straightforward, well-built way to get there.
This Marble Arms front sight is made for a standard 3/8" dovetail with a .531" barrel-mounted width. Many dovetail sights run slightly oversized on purpose, so you may need to fit it with a fine file for a snug seat. That tight fit is what keeps it locked in place under recoil.
Front sight height is measured from the bottom of the dovetail to the top of the bead, and .410" is Marble's baseline reference number in their sight-correction charts. The best move is to pull your current front sight and measure it with a caliper or micrometer. If your rifle is shooting high with the rear sight bottomed out, you'd want a taller sight, and vice versa.
Yes. The fiber optic cable is permanently flared into the solid steel body at both ends, and Marble treats it to resist UV fading from long-term sun exposure. You get the bright, easy-to-see green dot of a modern optic backed by a machined steel sight that can take a beating in the field.
Green tends to pop nicely against brown and dark backgrounds like timber and game, and a lot of folks find it easy on the eyes in variable light. Compared to a traditional brass or ivory bead, the glowing fiber optic gives you a faster, clearer aiming point, which is a real help for aging eyes. Marble offers the 41-MR in orange as well if you prefer that tone.
