Marble Arms No. 63H Dovetail Flat-Top Rear Sight, Short Shank

The Marble Arms No. 63H Flat-Top Dovetail Rear Sight in black is a short-shank replacement rear sight built for rifles with a standard dovetail-cut sight base. Marble Arms has been a fixture in American sporting rifle sights since the early 1900s, and the 63H pattern carries forward its classic flat-top notch profile favored by hunters who want a fast, uncluttered sight picture. The short shank keeps the sight low and close to the barrel, matching the profile of many factory-cut dovetail slots. Its black finish resists glare and blends with most factory rifle finishes.

Key Specifications

• The dovetail base drops into a standard factory-cut dovetail slot without additional machining.
• The flat-top notch profile gives a clean, fast sight picture favored by hunters over notched or buckhorn styles.
• A short shank keeps the sight body low and close to the barrel, matching many factory dovetail cuts.
• The black finish cuts glare and matches most factory rifle finishes.

Frequently Asked Questions

Will this sight fit any dovetail slot? It is sized for a standard factory dovetail cut, but dovetail widths vary by rifle model, so confirm your barrel’s dovetail width before ordering.

What does short shank mean on this sight? Short shank refers to the length of the sight body below the notch, which keeps this sight lower and closer to the barrel than a long-shank version.
