The Leupold Standard (STD) 1-Piece Scope Mount Base (Model LE178122) provides a highly secure and reliable foundation for mounting optics to your rifle. Specifically engineered for the iconic Browning BLR (Browning Lever Action), this base is designed to fit pre-1996 receiver layouts, commonly referred to as the Model 81. Machined from solid, forged steel, this low-profile mounting solution ensures a traditional, clean aesthetic on your lever-action rifle while maintaining maximum structural rigidity. The LE178122 model is finished in a durable matte black, sharing identical physical dimensions, strength profiles, and mounting tolerances with its gloss-finished counterpart.

Key Features:

• Dovetail and Windage Dual System: The forward section features a precision loop that accepts a twist-in dovetail front ring, locking it solidly in place, while the rear section is secured by two opposing windage-alignment screws.
• Bore-Sighting Adjustments: The rear opposing adjustment screws allow you to make physical lateral changes directly on the base during initial bore-sighting, saving the scope's internal click adjustments for precise field zeroing.
• Recoil Absorption: Crafted entirely from forged and machined steel to withstand the recoil forces of standard hunting calibers.
• Zero Maintenance Mechanics: Being a completely mechanical, high-grade steel accessory, this mount requires no batteries, has no electronic parts, and is completely free of Australian electrical safety compliance requirements, such as the Regulatory Compliance Mark (RCM).
• Optimal Eye Alignment: The low-profile build ensures your scope sits close to the barrel, preserving a comfortable, natural cheek weld on the Browning BLR stock.

Who It Is For:

This scope mount base is designed for Australian hunters, target shooters, and sporting firearms owners who shoot with the classic Browning BLR lever-action rifle. It is an ideal choice for those who demand a robust steel-on-steel connection that can handle rough transport and demanding field conditions across diverse Australian environments. Because pre-1996 and post-1996 Browning BLR receiver screw patterns vary, users should confirm their specific receiver layout matches this classic base configuration before mounting.
