Ruger 90678 Picatinny Rail 20 MOA Black Aluminum Short Action

The Ruger 90678 Picatinny Rail transforms your Ruger American Rifle into a precision shooting platform with its integrated 20 MOA cant. This factory-engineered rail system replaces the standard receiver-mounted bases to provide a continuous mounting surface for long-range optics. The built-in downward angle maximizes scope adjustment range for extended distance shooting.

What Makes This Different

Unlike aftermarket rails that require modification or shimming, this Ruger-manufactured rail integrates seamlessly with the American Rifle's receiver design. The 20 MOA built-in cant provides additional elevation adjustment without requiring angled scope rings or bases. The single-piece construction eliminates potential alignment issues between separate front and rear mounts while maintaining the rifle's factory accuracy standards.

Key Features

• Factory Ruger part engineered specifically for American Rifle short action models
• Integrated 20 MOA downward cant for long-range shooting applications

• Full-length Picatinny rail with multiple mounting positions

The 20 MOA cant proves particularly valuable for competitive precision rifle shooting and long-range hunting applications.

The rail accepts any standard Picatinny-compatible rings, providing flexibility in optic selection from tactical scopes to precision hunting glass.
