Marble Arms Rifle Dovetail #64 Semibuckhorn Shortshank Rearsight Blk
The Marble Arms Rifle Dovetail #64 Semibuckhorn Shortshank Rearsight is a classic iron sight upgrade for shooters who want to customize or refine their sight picture without optics. Built to fit standard 3/8" dovetail mounts found on many rifles, this rear sight gives you a straightforward way to replace factory sights, dial in a more precise sight picture, or add adjustability to a fixed-sight rifle. Whether you're tuning a hunting rifle, tending to a vintage gun, or just prefer iron sights on the range, the semi-buckhorn uprights deliver a traditional sight geometry that lets you focus downrange without complexity.
Marble Arms sights have earned their reputation through decades of use in the field. This #64 model pairs proven design with a shortshank base—compact enough for working guns yet robust enough for honest shooting. The semi-buckhorn profile is a middle ground: it offers more sight surface than a simple notch for windage and elevation tracking, but won't snag on gear or get in the way of your shooting hand. The black finish blends seamlessly with most rifle barrels and keeps glare down when you're trying to thread a tight sight picture.
Installation is straightforward on any rifle with a 3/8" dovetail—a common standard on classic and modern sporting rifles alike. If your gun runs iron sights or you want a backup to optics, this sight slides in where the original may have been, giving you a reliable aiming point that doesn't need batteries, zero creep, or wind adjustment. For hunters, competitors, and shooters who value simplicity and tradition, Marble Arms remains the go-to name in aftermarket iron sights.

Frequently Asked Questions
Will this rear sight fit my rifle?
The Marble Arms #64 is designed for rifles with standard 3/8" dovetail mounts. Before purchasing, verify your rifle has a 3/8" dovetail slot on the barrel or receiver. If you're unsure, check your rifle's manual or have a gunsmith confirm the dovetail size.
What is the difference between semi-buckhorn and other sight styles?
The semi-buckhorn uprights offer a wider sight surface than a simple V-notch, which can help you track windage and elevation more precisely and gather more light for shooting in lower conditions. It's a proven middle ground between minimalist and fully enclosed buckhorn designs.
Can I use this sight as a backup to a scope?
Yes. This rear sight works well as a secondary aiming method if your scoped rifle needs a backup, or as a primary sight on a rifle without optics. Its compact shortshank profile is designed to stay low and won't interfere with many typical scope mounts.
