The Leupold STD Winchester 70 RVF/R 2-Piece Matte Base (Part #50023 / LE50023) is a professional-grade steel mounting solution engineered specifically for post-war Winchester Model 70 rifles. Manufactured from forged and machined carbon steel, this two-piece base set provides a highly secure and stable platform for mounting optics. The distinctive feature of this model is its Reversible Front and Reversible Rear (RVF/R) configuration, which provides maximum flexibility when positioning scope rings. This capability makes it straightforward to mount shorter-bodied rifle scopes or adjust eye relief on both short and long action receivers without compromising stability or alignment.

Key Features:

• Reversible Front and Rear Bases (RVF/R): Both the front and rear bases can be reversed, enabling shooters to decrease or increase the distance between the mounting rings to accommodate compact scopes or optimize eye relief.
• Windage Adjustable Rear Base: Features lateral windage adjustment screws on the rear base, allowing users to make gross windage adjustments during installation and preserving the scope's internal click adjustments for precise field zeroing.
• Forged Carbon Steel Construction: Machined from solid steel blocks to deliver exceptional strength and structural integrity, finished in a non-reflective matte black to resist wear in tough environments.
• Elevation Shimming Compatibility: The design supports the placement of physical shims under the base, enabling gross elevation adjustments when setting up long-range optics.
• Zero MOA Bias: Designed with a flat 0 MOA cant, making it suitable for standard hunting ranges and general shooting applications.
