The Marble Arms #68 Full Buckhorn Longshank is about as classic as open rifle sights get. This is the pattern that came factory-installed on plenty of early Winchester lever guns, and it still turns a plain barrel into something that looks and shoots right. It drops into a standard 3/8" dovetail and works with bead-type or traditional blade front sights, so it's a natural fit for older rifles from Winchester, Marlin, Remington, Savage and plenty of others.
The full buckhorn wings wrap up high around the notch, which helps frame your front bead and block out distractions on either side. Up top you've got a reversible notch piece that flips between a U-shaped and a V-shaped notch, so you can pick whichever picture your eye prefers. A hand-painted white enamel diamond sits right below the notch to pull your eye straight to center for fast, instinctive alignment. It's a small touch that makes a real difference in low light or against a busy background.
Elevation runs off a double-step elevator that adjusts sight height from .300" to .510", and windage is handled by drifting the sight in its dovetail. The "longshank" part refers to the extended base that gives that step elevator room to work, which is why this one is the go-to when you need more elevation range than a fixed sight offers. Overall length is right around 3-1/8", and everything is machined from steel with a black finish.
Like most quality dovetail sights, this one may take a little minor fitting to seat properly in your barrel slot, and that's normal. Folks who've installed it often note it goes in cleanly and holds zero once it's set. If you're swapping out a worn factory sight or a peep you never bonded with, the #68 is a proven, all-steel upgrade with over a century of Marble Arms history behind it.
It's built for a standard 3/8" dovetail, which is the most common rear sight slot out there. That covers a wide range of rifles from Winchester, Marlin, Remington, Savage and others. As long as your barrel has a 3/8" dovetail and the barrel diameter works with the sight's height range, you're in good shape, though minor fitting is sometimes needed.
The notch piece is reversible, so you can flip it to run either a U-shaped or a V-shaped notch. A U notch tends to be a bit more forgiving and quicker to pick up, while a V notch can feel more precise for some eyes. You swap between them with a small screwdriver, so try both and keep whichever gives you the cleaner sight picture.
Elevation is handled by a double-step elevator that slides under the sight and props it up to different heights, giving you a range from .300" to .510". The "longshank" base is extended to give that elevator plenty of room to work. Windage is set separately by gently drifting the whole sight left or right in its dovetail.
It may take a little minor fitting to seat snugly in your barrel's dovetail, which is normal for quality replacement sights. A light touch with a file on the base is usually all it takes. Once it's set and drifted to zero, this all-steel sight holds its point of aim well.
