Leupold Standard 2-Piece Base for Winchester 70 RVF/R

Leupold Standard Steel Mounting Base

The Leupold Standard (STD) 2-piece base represents one of the most versatile scope mounting systems available to rifle shooters. Engineered for Winchester 70, 670, 770, and 770A actions, this base provides a rock-solid foundation for your optics.

Design and Construction

Forged and Machined Steel: Built from quality steel and finished in matte black, this base withstands the rigors of field use while maintaining a clean, professional appearance.

Ambidextrous Compatibility: Works equally well on right and left-hand actions, making it adaptable to your specific rifle configuration.

How It Works

The two-piece design separates mounting duties between front and rear:

• Front Base: Features a dovetail slot that accepts Leupold Standard rings, locking them solidly in position with a pivoting design
• Rear Base: Secured by windage adjustment screws, allowing you to fine-tune lateral alignment during bore-sighting without consuming your scope's internal adjustments

Practical Advantages

By using the rear windage screws for lateral adjustment, you preserve your scope's internal adjustments for precise sight-in and elevation compensation. Shims can be added under the base for gross elevation changes, further protecting your scope's adjustment range for bullet drop compensation applications.

Best Applications

Ideal for standard calibers under .300 Winchester Magnum. Pairs with Leupold Standard rings available in five different heights to match your specific rifle and optic combination.
