Marble Arms Rifle Flip-Up Rear Sight Black

The Marble Arms Rifle Flip-Up Rear Sight in black is a barrel-mounted backup sight designed for lever-action and single-shot rifles that need reliable iron sight fallback or primary aiming when glass isn't an option. Built with a folding design, this rear sight stays protected during storage and transport—flip it down when you're carrying or stowing your rifle, and raise it when you need to shoot. It's the kind of no-fuss accessory that doesn't get in the way until it matters.

The sight features a flat-top leaf with a white diamond insert that makes target acquisition faster and clearer than a plain blade. Windage adjustment is handled via drift and screw, so you can dial it in at the range without tools you don't have. What sets this Marble Arms sight apart is the long shank design paired with a center plate and locking screw—that means elevation adjustment is built in without needing a separate elevator piece. It's one less thing to buy and one fewer part to lose or break.

Marble Arms has been making rifle sights since the early 1900s, and their iron sights are still the standard backup for serious rifle hunters and shooters. This sight mounts to a standard 3/8" dovetail and may require minor fitting depending on your rifle's condition. Whether you're running a classic Winchester lever gun, a Sharps rifle, or any single-shot that shoots true, a quality rear sight like this one belongs in your kit.

Frequently Asked Questions

What rifles is this Marble Arms rear sight designed for?

This sight is built for lever-action and single-shot rifles that use a 3/8" barrel-mounted dovetail. Classic Winchester lever guns and Sharps-style rifles are popular choices. Minor fitting may be required depending on your rifle's dovetail condition.

Can I adjust elevation without a separate elevator piece?

Yes. The center plate with locking screw handles elevation adjustment, so you don't need to purchase or install a separate elevator. Windage is adjusted via drift and screw.

Will this sight stay out of the way when I'm not using it?

Exactly. The folding design lets you flip the leaf down when the rifle is stored or carried, keeping the sight protected and clear of snags. Raise it when you're ready to shoot.

What does the white diamond insert do?

The white diamond on the flat-top leaf makes the sight easier to acquire and align on target, especially in lower light or when you need quick shooting. It's a proven design detail that speeds up sight picture compared to a plain blade.
