Leupold 50021 Winchester 70 2-Piece Reversible Rear Base

Leupold Standard Steel Mounting System

The Leupold 50021 represents the pinnacle of versatility in rifle scope mounting. This 2-piece base system is engineered specifically for Winchester 70 rifles and delivers the precision and reliability that has made Leupold a standard in the shooting sports.

Key Features

• Reversible rear base design allows for flexible mounting configurations
• Windage adjustment screws on the rear ring enable precise lateral adjustment without disturbing your scope's internal adjustments
• Precision-engineered steel construction ensures consistent performance across standard calibers under .300 Win. Mag.
• Matte black finish provides a clean, professional appearance
• Shimming capability allows for gross elevation adjustment, preserving your scope's elevation turret for bullet drop compensation

Why This System Works

The front dovetail ring pivots to allow lateral adjustment during bore sighting—a practical feature that simplifies the initial setup process. By using the base's windage screws rather than your scope's internal adjustments, you preserve those adjustments for fine-tuning and long-range compensation.

This 2-piece base system pairs seamlessly with Leupold Standard rings, which are available in five different heights to accommodate various scope and rifle combinations. Whether you're setting up a hunting rifle or a target platform, this mounting system provides the foundation for consistent accuracy.

Compatibility
