Marble Arms .312'' Barrel Mounted 3/32'' 31-W Front Sight Brass Gold
$16.46
The Marble Arms .312" barrel mounted front sight is a time-tested option for rifles built with a dovetail slot milled directly into the barrel. This brass gold 31-W model delivers the clean, functional aesthetics Marble Arms has been known for since the early 1900s. The gracefully contoured blade slopes toward the front, reducing glare and improving sight picture in bright conditions. Steel construction and blued finish keep it corrosion-resistant and looking sharp on classic and modern rifles alike.
Barrel-mounted front sights sit lower than ramp-based alternatives, making them ideal for rifles where the dovetail slot is cut into the barrel itself rather than a separate ramp. The rounded base sides of this "W" pattern sight ensure a solid fit in standard barrel dovetails without binding or looseness. At 17/32" (13.5mm) wide, the base provides ample bearing surface for reliable, repeatable positioning.
Whether you're setting up a rifle for hunting, target shooting, or restoration work, this Marble Arms sight offers proven reliability without unnecessary complexity. The brass gold finish adds a touch of character while the steel construction handles recoil and weather without complaint. If your rifle has the classic dovetail cut directly into the barrel and needs a solid iron sight solution, this one checks the box.

Frequently Asked Questions
Will this sight fit my rifle?
This sight is designed for rifles with a dovetail slot milled directly into the barrel (not for ramp-mounted systems). Your barrel must have the proper .312" dovetail cut to accept this sight. If you're unsure whether your rifle has a barrel dovetail, check your rifle's manual or have a gunsmith verify the cut before ordering.
What's the difference between barrel-mounted and ramp-mounted front sights?
Barrel-mounted sights like this one attach directly to the barrel via a dovetail slot, sitting lower on the gun. Ramp-mounted sights attach to a separate base that sits atop the barrel. This particular sight is a barrel-mounted design, so it requires the dovetail to be cut into the barrel itself.
Can I use this on a modern tactical rifle?
This is a traditional iron sight designed for rifles with barrel dovetail cuts, typically found on classic rifles, vintage bolt-actions, and rifles built to traditional specifications. Most modern tactical rifles use Picatinny rails or other mounting systems. Check your rifle's barrel and mounting system before purchasing.
