Marble Arms .375'' Barrel Mounted 3/32'' 37-W Front Sight Steel White

The Marble Arms .375'' Barrel Mounted Front Sight with 3/32'' white bead is a classic iron sight solution for rifles that need a no-fuss, reliable aiming point. Built to mount directly into dovetail cuts on the barrel itself, this steel front sight delivers the kind of solid performance that's kept shooters on target for generations. Whether you're working with a vintage rifle, a modern build, or anything in between, a quality barrel-mounted front sight remains one of the most durable and weather-proof aiming options available.

This particular model features a gracefully contoured blade design that slopes toward the front for a clean sight picture. The 3/32'' white polymer bead provides excellent visibility in varied light conditions—bright enough to pick up quickly but not so bold that it obscures your target. The rounded base sides are specifically engineered to fit rifles with barrel-mounted dovetail cuts, and the "W" designation indicates a 17/32" (13.5mm) wide base, a common standard for many rifle platforms.

Steel construction with a clean blued finish means this sight will hold up to field use and won't distract from your rifle's aesthetics. Unlike electronic or prismatic sights, there's nothing to fail, no batteries to die, and no complexity to fuss with—just a straightforward, tactile aiming solution. Marble Arms has built their reputation on no-nonsense iron sights, and this front sight carries on that tradition.

Frequently Asked Questions

Will this front sight fit my rifle?

This sight is designed for rifles with a barrel-mounted dovetail cut. The rounded base sides and 17/32" (13.5mm) width ("W" configuration) fit the standard dovetail configuration found on many traditional and modern barrel-mounted platforms. Verify your rifle has a barrel dovetail slot before ordering.

How visible is the white bead in low light?

The 1/16" white polymer bead is flat-faced and provides good visibility across typical hunting and range conditions. White beads offer more light reflection than darker options, making them easier to pick up quickly. In very low light, any front bead becomes harder to see—consider your typical shooting environment.

Can I use this sight with a rear sight?

Yes, barrel-mounted front sights are designed to work with rear sights. The specific rear sight compatibility depends on your rifle's configuration and where the rear sight is mounted (barrel, receiver, or ramp). Verify that your intended rear sight setup won't interfere with this front sight's height and position.

Is this sight included with anything or sold standalone?

This is a standalone front sight. It does not include a rear sight or mounting hardware beyond what's needed for dovetail installation.
