Marble Arms .500'' Ramp Mounted 1/16'' 50-Mr Front Sight Brass Gold

The Marble Arms .500" Ramp Mounted 1/16" 50-MR front sight is a classic, no-frills open sight built for rifles equipped with a barrel ramp base. If you're running a vintage lever-action, classic-era bolt gun, or any rifle with a ramp-style front sight base, this blade delivers the dependable aiming reference that made Marble Arms a go-to name for generations of hunters and shooters. The contoured profile tapers toward the front, keeping sight picture clean and uncluttered—exactly what you want when you're focusing on the target, not the hardware.

Construction is solid steel with a durable blued finish that both protects against the elements and complements traditional rifle aesthetics. The brass gold bead catches available light without being overly bright or distracting, making it easier to pick up on game or at the range across variable lighting conditions. At .500" height, this sight integrates seamlessly with rifles designed for ramp-mounted front sights and pairs naturally with most corresponding rear sights in the Marble Arms lineup.

Whether you're restoring a classic rifle, building a truck gun, or simply prefer the reliability and speed of open iron sights over optics, a quality front sight matters. The Marble Arms MR series has earned trust on hunting trips and shooting ranges for decades because it does one job and does it right—give you a solid, repeatable aiming point without complications or batteries.

Frequently Asked Questions

Will this front sight work on my rifle?

This sight is designed for rifles with a barrel ramp base. Check whether your rifle has a ramp-style front sight base (typical on lever-actions and some classic rifles) versus a dovetail or other mounting style. If your barrel is equipped with a ramp, the .340" wide base of the 50-MR will fit.

What rear sight pairs with this front sight?

Marble Arms makes complementary rear sights in their MR series. Since this is a .500" height sight, you'll want a rear sight from the same manufacturer and series to ensure proper sight picture alignment. Check the specifications of your chosen rear sight against this front sight's height.

Is this sight adjustable?

This is a fixed front sight. Windage and elevation adjustment is typically handled by the rear sight. Marble Arms rear sights often include elevation and windage capabilities to dial in your zero.

Why choose iron sights over a scope?

Open iron sights are fast, rugged, require no batteries, and work in any weather or light. They're ideal for hunting in close cover, brush work, or as a backup to optics. Many hunters and shooters prefer the simplicity and reliability of irons for shorter-range work.
