Description
The Marble Arms #65 Full Buckhorn Short Shank Rear Sight is one of those parts that's been around forever for good reason. This is the short-shank version of Marble's classic sporting rear, built from black-finished steel with the tall, curved buckhorn wings that wrap up and inward like antler tips. Those wings help pull your eye toward center, giving you a semi-peep effect for quick shots while the notch at the bottom handles precise aiming. It's the same design that shipped on countless factory rifles from the golden age of lever guns, and Marble still hand-finishes them today.
What the #65 Buckhorn Brings to the Table
The short shank measures roughly 1-7/8 inches, which puts the sight forward on the barrel and keeps it clear of the receiver on carbines and shorter actions. You get real elevation adjustment thanks to the step elevator, which slides through a range of about .300 to .510 inch so you can dial in your zero without filing anything. Windage is handled by drifting the base in the dovetail. Marble's reversible notch piece and the hand-painted enamel diamond are part of the package too, and that little diamond does a surprisingly good job of drawing your eye straight to the notch for fast, instinctive shooting.
Fitting the Marble Arms #65 to Your Rifle
This one drops into a standard 3/8" 60-degree dovetail, which covers a huge range of rifles from Winchester, Marlin, Remington, Savage and plenty of others. As with most quality dovetail sights, expect to do a little light fitting to get a clean, tight tap-in fit. A set of small files, a plastic drift or wood dowel, and some patience is all it takes. Remove the forearm before drifting anything and go slow.
If you're chasing that traditional iron-sight look on a lever action or an older bolt gun, or you just want a rear sight with genuine adjustment and character, the full buckhorn #65 is a proven pick that shooters keep coming back to.

Frequently Asked Questions
What rifles does the Marble Arms #65 full buckhorn rear sight fit?
It's built for a standard 3/8" 60-degree dovetail, which is what you'll find on a wide range of rifles from Winchester, Marlin, Remington, Savage and many others. That covers a lot of lever guns and older bolt actions. Since it drops into the common dovetail size, it works as a direct-style replacement on most rifles cut for one, though a little fitting is normal.
How is a full buckhorn different from a semi-buckhorn sight?
A full buckhorn has taller wings that curve up and inward toward each other, almost forming a ring around the notch, while a semi-buckhorn has shorter wings that stay flatter and more open. The full buckhorn gives you a sort of semi-peep effect for quick target acquisition, with the bottom notch handling fine aiming. Which you prefer often comes down to your eyes and how much of the target you want to see around the sight.
Does the #65 rear sight have elevation adjustment?
Yes. It comes with Marble's step elevator that raises and lowers the sight through a range of roughly .300 to .510 inch, so you can zero it without filing the sight down. Windage is set by drifting the base left or right in the dovetail.
Will I need to modify anything to install the Marble Arms #65?
Most likely just a little light fitting. Dovetail sights are made slightly oversized so they lock in tight, so a bit of careful filing on the base is common to get a clean tap-in fit. Take the forearm off first, use a plastic drift or wooden dowel, and go slow so you don't overdo it.
