Leupold QRW 2-Piece Scope Bases for Winchester Model 70 Rifles: Unyielding Precision for Demanding Shooters

For serious shooters and hunters who demand uncompromising accuracy and rock-solid stability from their optics, the Leupold 49838 QRW 2-Piece Scope Bases are an indispensable component. Specifically engineered to provide a robust and repeatable mounting platform for Winchester Model 70, Model 670, Model 770, and Model 70A rifles, this system stands as a testament to Leupold’s legacy of rugged American manufacturing and optical excellence. If you’ve ever found yourself asking, "What's the most reliable scope base for my Winchester Model 70, especially if I'm using magnum calibers?" or "How can I ensure my scope holds zero even after repeated heavy recoil or quick optic removal?", then you've found your definitive answer.

This isn't just another set of scope bases; it's a precision-engineered foundation designed to maximize the performance of your rifle and optic system. Whether you’re a long-range enthusiast, a dedicated big-game hunter pursuing elusive quarry in challenging conditions, or a tactical shooter requiring absolute dependability, the QRW (Quick Release Weaver-style) system offers the confidence that your aiming point remains true, shot after shot.

Why Leupold QRW Bases are Essential for Your Winchester Model 70

The Leupold 49838 QRW 2-Piece Base system addresses critical concerns for rifle owners. Here’s how it solves common challenges and enhances your shooting experience:

• Unwavering Zero Retention: The primary concern for any shooter is maintaining zero. These steel bases, combined with Leupold’s precision manufacturing, create an exceptionally stable interface between your rifle and your scope. This rigidity is paramount when dealing with the significant recoil generated by standard to magnum calibers, preventing the subtle shifts that can throw your shot off target.
• Quick Release Functionality with Repeatable Accuracy: The "QRW" in its name signifies "Quick Release Weaver-style." This isn't just a convenience; it's a strategic advantage. You can effortlessly remove your optic from the rifle and re-attach it later with an astonishingly precise return to zero, often within 1/4 MOA. This feature is invaluable for:
  • Cleaning and Maintenance: Easily access the rifle’s action for thorough cleaning without disturbing your scope’s zero.
  • Transportation: Remove the scope to protect it from bumps and knocks during transport or storage.
  • Versatility: Quickly swap between different optics (e.g., a low-power variable optic for close-range hunting and a high-power scope for long-range target shooting) on the same rifle, or even use iron sights if conditions demand.
• Superior Durability and Strength: Constructed from high-quality steel, these bases are built to withstand the harshest environments and the most powerful recoil forces. Unlike lighter aluminum alternatives that might flex under extreme stress or repeated heavy use, steel provides a level of integrity and longevity that ensures your mounting system will outlast your rifle. The matte black finish further adds to its resilience by reducing glare and resisting corrosion.
• Optimal Compatibility and Versatility: The Cross-Slot design allows for seamless integration with both Weaver and Picatinny-style rings, providing maximum flexibility when choosing your scope rings. This universal compatibility ensures you aren't limited in your choice of optic or ring solutions. The 2-piece design offers flexibility in scope placement, accommodating a wide range of scope lengths and eye relief requirements, while also allowing easier access to the rifle's ejection port and chamber for loading, unloading, and malfunction clearing.
• Engineered for Winchester Model 70 Series: These bases are custom-tailored for a perfect fit on Winchester Model 70, 670, 770, and 70A rifles. This precise fit eliminates any play or wobble, contributing directly to the system's overall stability and accuracy. When you invest in a firearm of the Winchester Model 70's caliber, you want mounting hardware that matches its pedigree.

Delving Deeper: The Leupold Advantage in Scope Mounting Systems

Leupold has been a leading name in optics and mounting solutions for generations, synonymous with trust, innovation, and performance. Their commitment to excellence is evident in every product, including the QRW bases.

• Cross-Slot Technology: This advanced design is a cornerstone of Leupold’s robust mounting solutions, including the PRW2, LRW, and Open Range series. It ensures a stronger, more consistent lock-up with your rings, effectively distributing recoil forces and minimizing stress on your optic. This technology is a significant upgrade from older, less secure mounting methods.
• American Craftsmanship: Leupold products are designed, machined, and assembled in the USA, adhering to rigorous quality control standards. This commitment to domestic manufacturing translates into superior quality, greater reliability, and confidence for the end-user.
• Lifetime Performance: Leupold stands behind its products. While the specific warranty details for mounting hardware should always be confirmed, Leupold's reputation for customer support and product longevity is unmatched in the industry. Choosing Leupold means choosing a product engineered for a lifetime of dependable use.

Installation and Maintenance Tips for Your Leupold QRW Bases

Proper installation is crucial for maximizing the performance of your Leupold QRW bases. While professional installation is always recommended for those unfamiliar with gunsmithing, here are general guidelines:

1. Preparation: Ensure your rifle is unloaded and the chamber is clear. Gather necessary tools, including a torque wrench, Loctite (non-permanent blue), and the mounting hardware included with your bases.
2. Clean Surfaces: Thoroughly clean the receiver's mounting holes and the base's underside with a degreaser to ensure a proper bond.
3. Position Bases: Place the bases on the receiver, ensuring correct orientation (typically, the longer base goes on the rear). The two-piece design allows for precise alignment.
4. Secure Screws: Apply a small amount of blue Loctite to the threads of the mounting screws. Hand-tighten all screws initially to ensure they are properly seated.
5. Torque to Specification: Using a quality torque wrench, tighten the screws to the manufacturer’s recommended torque specifications. Over-tightening can strip threads or damage components, while under-tightening can lead to instability. Refer to the specific instructions provided with your bases or rings.
6. Mount Rings and Optic: Once the bases are securely installed, you can proceed to mount your Leupold QRW-compatible rings and then your preferred rifle scope. Always follow the torque specifications for your rings as well.
7. Regular Inspection: Periodically check all mounting screws for tightness, especially after periods of heavy use or significant recoil. A loose screw can quickly degrade accuracy.

Maintaining your Leupold QRW bases is straightforward. Simply wipe them down after use to remove any moisture, dirt, or debris. A light coat of gun oil can protect the steel from corrosion, particularly if operating in humid or wet conditions. The robust matte black finish is designed for durability, but proper care will extend its aesthetic life and protective qualities.
