Leupold STD Two-Piece Base for Browning BLR

Leupold Standard Two-Piece Base System

Leupold's steel Standard (STD) bases represent one of the most versatile mounting systems available for precision rifle shooting. This two-piece design is specifically engineered for Browning BLR rifles and works perfectly with standard calibers up to .300 Winchester Magnum.

Key Features

• Forged and machined steel construction for durability and reliability
• Two-piece design with dovetail front ring for solid, repeatable positioning
• Windage adjustment screws on the rear ring allow lateral scope adjustment during bore-sighting
• Fits both right and left-hand actions
• Matte black finish resists glare and corrosion
• Compatible with STD rings in five different heights for optimal scope positioning

Design Philosophy

The STD base system's rear windage adjustment allows you to reserve your scope's internal adjustments exclusively for precise sight-in and elevation compensation. This separation of duties means your scope's elevation dial remains available for bullet drop compensation—a critical advantage for hunters and long-range shooters.

Shims can be used for gross elevation adjustments, further preserving your scope's adjustment range for field use. The front dovetail ring locks solidly into position while allowing the rear ring to pivot for lateral adjustment.

The Right Choice

If you're mounting a quality scope on your Browning BLR, Leupold's Standard bases deliver the precision and versatility serious shooters demand.
