Who Needs a Leupold QRW Base Set for their Winchester Model 70?

If you own a Winchester Model 70 rifle and seek a superior scope mounting solution, this Leupold QRW Base Set is designed specifically for your needs. It’s an indispensable upgrade for:

• Hunters: Imagine the convenience of quickly removing your primary hunting scope for cleaning or to switch to a low-light optic as dusk approaches, all without losing your painstakingly set zero. The Leupold QRW system makes this a reality, ensuring you're always ready for the shot.
• Competitive Shooters: In dynamic shooting disciplines where versatility and adaptability are key, the ability to swap optics swiftly and accurately can be a game-changer. Whether transitioning between iron sights and a magnified optic or changing scopes for different stages, the QRW system offers unparalleled efficiency.
• Tactical Operators and Enthusiasts: For applications demanding rapid configuration changes and unwavering durability, the steel construction and precise machining of these bases provide the resilience needed in demanding environments.
• Firearms Enthusiasts and Collectors: For those who appreciate the heritage and performance of the Winchester Model 70, equipping it with a Leupold mounting system ensures that the rifle's inherent accuracy potential is fully realized and preserved.
• Anyone Concerned with Zero Retention: The primary problem this product solves is the common concern of maintaining scope zero after removal and reattachment. Traditional mounts can sometimes shift, but Leupold's QRW technology guarantees repeatable precision.

Unpacking the Advanced Technology: What Makes QRW Bases Stand Out?

At the core of the Leupold QRW Base Set's exceptional performance lies its ingenious design, rooted in Leupold's proprietary Cross-Slot mounting system. This system incorporates Quick Release Weaver-style rings (though rings are sold separately, these bases are designed to seamlessly integrate with them) that are compatible with both Weaver and Picatinny rails.

Key Technological Advantages:

• Quick Release Capability: The hallmark feature. Unlike fixed mounts that require tools and careful re-alignment, the QRW system allows for rapid attachment and detachment of your scope. This means you can easily:
  • Swap between different optics (e.g., a high-magnification scope for long-range target shooting and a lower-power optic for brush hunting).
  • Remove your scope for thorough rifle cleaning, especially in areas otherwise obscured by the optic.
  • Store your rifle and optic separately for transport or security without complicated re-zeroing upon reassembly.
  • Access backup iron sights quickly if your primary optic becomes damaged or fails in the field.
• Unrivaled Repeatability (± 1/4 MOA Accuracy): This is where Leupold truly shines. The QRW2 system, a direct evolution of their renowned QR mounts, boasts an impressive +/- 1/4 MOA accuracy when removing and replacing your optic. What does this mean for you? It means that once you've sighted in your rifle, you can detach your scope and reattach it with confidence, knowing that your point of impact will return to within a quarter minute of angle of its original zero. This level of precision is critical for maintaining consistent performance, whether on the range or in the field.
• Robust Steel Construction: The Leupold QRW bases are crafted from high-quality steel, a material chosen specifically for its superior strength and durability. Steel provides:
  • Exceptional Recoil Resistance: It can withstand the repeated shock and vibration of magnum calibers (which the Winchester Model 70 is often chambered in) without deforming or losing its integrity.
  • Longevity: These bases are built to last a lifetime, enduring harsh weather conditions, accidental impacts, and rigorous use.
  • Secure Mounting: The inherent rigidity of steel ensures a stable platform for your optic, minimizing flex and maximizing accuracy.
• Versatile Picatinny/Weaver Compatibility: The Cross-Slot design allows the QRW bases to accept a wide array of Weaver-style or Picatinny-compatible scope rings. This universal compatibility ensures you're not locked into a specific ring manufacturer, offering flexibility in choosing the best rings for your specific scope.
• Two-Piece Design: The Leupold QRW Base Set comes as a two-piece system. This design offers several advantages, including:
  • Enhanced Receiver Access: Allows for easier access to the rifle's action for cleaning, maintenance, or single-loading.
  • Reduced Weight: Typically lighter than one-piece mounts, contributing minimally to the overall rifle weight. At a mere 1.80 oz, these bases add negligible mass while providing immense strength.
  • Flexibility in Eye Relief: A two-piece system can sometimes offer more flexibility in positioning your scope to achieve optimal eye relief, depending on the scope and rifle configuration.

Installation Insights: Securing Your Optics with Confidence

Proper installation is crucial to maximizing the benefits of your Leupold QRW Base Set. While these bases come with all necessary mounting hardware, it is highly recommended to follow best practices for optic installation to ensure secure fitment and repeatable accuracy.

General Installation Best Practices:

• Clean Surfaces: Ensure the rifle receiver's mounting holes and the base's mating surfaces are clean and free of oil or debris. Use a degreaser if necessary.
• Thread Preparation: Apply a small amount of non-permanent threadlocker (e.g., blue Loctite) to the base screws before installation. This prevents screws from backing out under recoil.
• Torque Specifications: Always adhere to the manufacturer's recommended torque specifications for the base screws. While specific torque values can vary, typical rifle scope base screws are torqued to around 15-20 inch-pounds. Using a quality torque wrench is essential to prevent over-tightening (which can strip threads or deform components) or under-tightening (which can lead to movement under recoil).
• Secure Fitment: Ensure the bases are seated squarely and firmly on the receiver. The robust steel construction is designed for a precise fit with the Winchester Model 70's receiver.

By following these steps, you establish a rock-solid foundation for your scope, allowing the Leupold QRW system to deliver its promised repeatability and zero retention.

Elevating Your Shooting Experience: Why Leupold QRW Matters

Consider the scenarios where the Leupold QRW Base Set truly makes a difference:

• Rapid Scope Swap for Changing Conditions: Imagine you are deer hunting. Early morning, you need a high-power scope for a distant shot across a field.

Beyond the Basics: Care and Maintenance

To ensure the longevity and continued performance of your Leupold QRW Base Set, simple care and maintenance are recommended:

• Regular Cleaning: After use, especially in wet or dirty conditions, wipe down the bases with a clean, dry cloth. A light coat of rust-preventative oil can be applied to the steel surfaces, particularly in humid environments.
• Check Torque: Periodically check the torque of the base screws. While threadlocker helps, recoil and environmental changes can sometimes affect screw tension over time. A quick check before a hunting trip or a shooting session can prevent issues.
• Inspect for Damage: Visually inspect the bases for any signs of wear, corrosion, or impact damage. While steel is incredibly durable, proactive inspection helps catch potential issues early.
