Marble Arms Rifle Dovetail #67H Semibuckhorn Longshank Rearsight Blk

The Marble Arms Rifle Dovetail #67H Semibuckhorn Longshank Rearsight is a true drop-in replacement rear sight for rifles with standard 3/8" dovetail mounting systems. Whether you're restoring a classic rifle, upgrading from factory fixed sights, or fine-tuning your sight picture on a gun that wasn't quite right from the factory, this semibuckhorn-style sight gives you a proven, no-nonsense aiming solution that's been trusted by shooters for generations. The longshank uprights and semibuckhorn profile deliver a clean, functional sight geometry without unnecessary complications.

Marble Arms has been making rifle sights since the early 1900s, and this #67H reflects that deep heritage of reliability. The semibuckhorn design offers a defined notch for precision aiming and the taller longshank configuration works well on rifles where standard sight heights need adjustment. Installation is straightforward for anyone comfortable with basic gunsmithing—it slides into the dovetail and is secured with the included or existing dovetail base mechanism.

This is the kind of sight that appeals to hunters, vintage rifle enthusiasts, and shooters who prefer mechanical aiming systems. It doesn't require batteries, electronics, or adjustments that can shift in the field. If your rifle already has a dovetail cut and your sight picture needs correction or upgrade, or if you're building out a rifle that came without rear sights, the Marble Arms #67H is a time-tested option that won't let you down.

Frequently Asked Questions

Will this rear sight fit my rifle?

Yes, if your rifle has a standard 3/8" dovetail cut on the barrel or receiver. Marble Arms semibuckhorn sights are designed for this common dovetail specification found on many hunting rifles and vintage firearms. If you're unsure whether your rifle has a 3/8" dovetail, measure the dovetail slot or consult your rifle's manual.

What's the difference between semibuckhorn and other Marble Arms sight styles?

The semibuckhorn profile offers a defined notch for aiming—not as deep as a full buckhorn, which makes it ideal for shooters who want a clear sight picture without excessive bulk. The exact upright geometry is what sets the semibuckhorn apart from other available styles Marble Arms offers.

Is the longshank height compatible with standard rifle stocks?

Longshank uprights provide greater height than standard versions, making them suitable for rifles where proper cheek weld and line of sight need adjustment. Compatibility depends on your specific rifle stock and barrel profile; we recommend confirming sight height specifications against your rifle's geometry before purchase.

Can I install this myself, or do I need a gunsmith?

Installation into an existing dovetail is straightforward for someone with basic gunsmithing experience. If your rifle doesn't already have a dovetail cut, or if you're uncomfortable making the installation yourself, a gunsmith is the right choice.
