Marble Arms Rifle Flip-Up No. 69H Flat Top Black

The Marble Arms Rifle Flip-Up No. 69H Flat Top Black is a compact rear sight built for shooters who need a low-profile backup or primary aiming solution. This is a folding leaf sight designed to sit flush against your rifle when not in use, then flip up when you need it—ideal for hunters, tactical shooters, and anyone running a flat-top receiver without a carry handle. The reversible notch lets you choose between a U-notch and V-notch configuration, so you can dial in your preferred sight picture without swapping parts.

Like all Marble Arms sights, the No. 69H features a strong spring detent that locks the sight firmly in either the up or down position—no wobble, no drift. The sight mounts via standard rifle dovetail, and the flat-top design sits slightly higher than conventional folding leaf sights, giving you a better cheek weld and sight picture on modern rifle platforms. Available in two height ranges (.460" to .590" overall), this sight is compatible with most standard rear sight dovetails, making it a drop-in upgrade for AR-15s, AK platforms, and other rifles with dovetail mounting provision.

Marble Arms has been making quality iron sights since the early 1900s, and it shows in the fit and finish. The No. 69H is a solid, no-nonsense sight that doesn't require batteries, electronics, or anything fancy—just honest mechanical reliability. Whether you're setting up a truck gun, a backup system for a scoped rifle, or going all-iron, this sight will outlast you.

Frequently Asked Questions

Will the No. 69H fit my rifle's dovetail?

The No. 69H is designed to fit most standard rifle rear sight dovetails. If your rifle uses a standard dovetail mount (common on AR-15s, AKs, and many hunting rifles), this sight should be compatible. If you have a non-standard or proprietary rail system, verify dovetail compatibility before purchase.

What's the difference between the U-notch and V-notch?

The reversible notch piece lets you flip it to choose your preferred sight picture. The U-notch provides a wider, more forgiving sight picture for faster target acquisition, while the V-notch offers a more precise aiming point for accuracy at distance. You get both options in one sight.

Is this sight taller than standard folding sights?

Yes. The No. 69H is designed for flat-top receivers and sits .096" higher than conventional folding leaf sights, giving you proper sight height and cheek weld on modern rifle platforms.

Does the sight stay locked in the down position?

Yes. The strong spring detent holds the sight securely in either the up or down position, so it won't flip or rattle when folded.
