Marble Arms Rifle Dovetail #68 Fullbuckhorn Longshank Rear Sight Blk

The Marble Arms Rifle Dovetail #68 Fullbuckhorn Longshank Rear Sight is a classic-style rear sight built for hunters and shooters who want reliable iron sights on rifles with standard dovetail bases. Whether you're restoring a vintage rifle, replacing worn sights, or adding backup iron sights to a modern hunting rifle, this fullbuckhorn-style sight delivers the adjustability and sight picture that work in the field. The longshank configuration gives you the proper sight radius and cheek weld on rifles designed for traditional rear sights.

Marble Arms has been making quality iron sights since 1906, and this #68 model carries on that tradition with a robust, no-frills design that handles hard use. The fullbuckhorn upright offers a wide, forgiving sight notch—practical for hunting where you need quick target acquisition in variable light. The sight mounts into any standard 3/8" dovetail, making it a straightforward swap on countless rifle platforms. All-steel construction in black means it'll hold zero and stand up to recoil season after season.

This is the kind of sight that doesn't need batteries, doesn't require a special mounting base, and won't fail when it matters. Pair it with a quality front sight and you've got a hunting rifle or range gun with sights you can trust.

Frequently Asked Questions

Will this rear sight fit my rifle?

The Marble Arms #68 is designed for rifles with standard 3/8" dovetail slots. Check your rifle's receiver or barrel to confirm you have a 3/8" dovetail before ordering.

What is a fullbuckhorn sight, and is it right for hunting?

A fullbuckhorn upright features a wide, U-shaped notch at the top. The broad sight picture is fast to pick up and forgiving in variable hunting light, making it popular for field rifles where speed and simplicity matter more than target-range precision.

Can I use this sight on a modern rifle?

Does this sight come with a front sight?

This listing is for the rear sight only. You will need to source a compatible front sight separately, or verify that your rifle already has a front sight installed.
