Leupold STD One-Piece Base Winchester 70A Matte

Leupold Standard One-Piece Steel Base

Leupold's Standard (STD) steel bases represent the gold standard in rifle scope mounting systems. This one-piece design is engineered specifically for Winchester 70A long action rifles and delivers the stability and precision that serious shooters demand.

Key Features

• One-piece steel construction provides superior rigidity and alignment stability compared to two-piece systems
• Windage adjustment capability via rear screws allows you to fine-tune scope alignment during bore-sighting without using the scope's internal adjustments
• High-grade steel construction withstands recoil from standard calibers up to .300 Winchester Magnum
• Precision engineering ensures perfect alignment with Leupold STD rings (available in five different heights)
• Matte black finish resists glare and corrosion

Why Choose STD Bases?

The front dovetail ring pivots for lateral adjustment, giving you flexibility during setup and bore-sighting. By reserving your scope's internal adjustments for final zeroing, you maintain maximum adjustment range for field use. The one-piece design eliminates the potential for misalignment that can occur with two-piece systems.

Backed by Leupold's reputation for quality and durability, this base will hold zero through years of hunting, target shooting, and all-weather use.
