Engineered for Excellence: Key Features and Design Advantages

The Weaver 99476 Multi-Slot Extended Base is not merely a piece of metal; it's a meticulously engineered component crafted to meet the exacting demands of modern shooting. Its design incorporates several critical features that contribute to its superior performance and adaptability:

1. Multi-Slot (Picatinny/Weaver Compatible) Design

At the heart of the 99476's versatility is its multi-slot configuration. This design adheres to both Picatinny and Weaver rail standards, making it universally compatible with a vast array of scope rings and optic mounting systems. This means you are not limited to a specific brand or style of rings; you can choose the ones that best suit your scope, your budget, and your shooting preference.

• Unparalleled Optic Versatility: Whether you prefer traditional rifle scopes, red dot sights, magnified optics with larger objective bells, or even tandem mounting systems (though less common on a single rail), the multi-slot design accommodates them all. This future-proofs your rifle, allowing you to easily swap optics as your needs or disciplines evolve without having to replace the base.
• Precise Eye Relief Adjustment: The numerous slots along the rail provide an extensive range of mounting positions for your scope rings. This is absolutely critical for achieving optimal eye relief – the ideal distance between your eye and the scope's eyepiece. Correct eye relief prevents "scope bite" and ensures a full, clear sight picture, which is essential for rapid target acquisition and sustained comfort during extended shooting sessions. An "extended" base amplifies this benefit, providing even more forward and rearward adjustability than standard bases.
• Consistent Zero Retention: The robust engagement between the rail slots and your scope rings minimizes any potential for movement, even under heavy recoil. This contributes directly to superior zero retention, meaning your scope will hold its point of impact reliably, shot after shot, season after season.

2. Extended Length Configuration

The "Extended" aspect of the Weaver 99476 is a significant advantage, particularly for rifles like the Winchester XPR Long Action, which often accommodate larger scopes or demand specific eye relief setups.

• Accommodates Larger Optics: Modern long-range and hunting scopes often feature larger objective lenses, longer main tubes, and more complex turrets. An extended base provides the necessary real estate to mount these scopes without interference, ensuring proper balance and optimal weight distribution.
• Enhanced Eye Relief Flexibility: As mentioned, the extended length provides a greater range of fore and aft adjustment for your scope. This is particularly beneficial for shooters who may have unique anatomical needs, wear corrective lenses, or use a rifle in various shooting positions (prone, bench, standing), each potentially requiring a slight adjustment to eye relief.
• Forward Mounting Capability: For certain shooting styles, or when using night vision or thermal clip-on devices, the ability to mount your primary optic further forward can be crucial. The extended design facilitates this, offering adaptability that a standard-length base simply cannot.

3. Robust One-Piece Construction

Unlike two-piece bases that require precise alignment and can sometimes suffer from minor flex, the Weaver 99476 is a single, monolithic piece of equipment.

• Unwavering Stability: A one-piece design inherently offers superior rigidity and stability. It eliminates potential weak points found in multi-part systems, ensuring that your scope mount acts as a single, unyielding bridge between your rifle's receiver and your optic. This translates directly to enhanced accuracy and consistent shot placement.
• Enhanced Recoil Resistance: The single-piece construction distributes recoil forces more effectively across the entire mounting surface, reducing stress on individual screws or contact points. This design characteristic is vital for maintaining zero, especially when firing powerful long action cartridges.
• Simplified Installation: While two-piece mounts can be effective, a one-piece base often simplifies the installation process, reducing the chances of misalignment and ensuring a more secure fit from the outset.

4. Precision-Machined Aerospace-Grade Aluminum

The choice of material is paramount for any scope mount. The Weaver 99476 is crafted from high-strength, lightweight aerospace-grade aluminum.

• Optimal Strength-to-Weight Ratio: This material provides exceptional strength and rigidity without adding unnecessary bulk or weight to your rifle. In hunting scenarios or long treks, every ounce matters, and a lightweight yet robust mount is a significant advantage.
• Corrosion Resistance: Aluminum naturally exhibits excellent resistance to rust and corrosion, an essential attribute for gear exposed to the elements, moisture, and varying temperatures in the field.
• Durability and Longevity: The inherent properties of aerospace aluminum ensure that the mount can withstand significant abuse, impacts, and environmental stressors, providing reliable service for years to come.

5. Durable Black Anodized Finish

The mount is finished with a hard-coat black anodizing process.

• Enhanced Surface Hardness: Anodizing creates a tough, scratch-resistant surface that protects the aluminum from abrasion and minor impacts, preserving the mount's aesthetic and functional integrity.
• Corrosion Protection: This finish adds an additional layer of protection against environmental degradation, ensuring the mount remains pristine even after prolonged exposure to harsh conditions.
• Reduced Glare and Reflection: The matte black finish is non-reflective, crucial for hunters and tactical shooters who need to maintain a low profile and avoid unwanted glare that could alert game or adversaries.

Unlocking Your Rifle's Full Potential: Performance Benefits

Integrating the Weaver 99476 Multi-Slot Extended Base into your Winchester XPR Long Action setup provides tangible performance enhancements that directly impact your success in the field or at the range.

• Pinpoint Accuracy and Unwavering Zero Retention: The primary benefit of a high-quality scope base is its contribution to accuracy. By providing an incredibly stable and rigid platform, the 99476 minimizes any movement between your rifle and optic. This means your scope's zero will hold true, allowing for consistent shot placement and confidence in every pull of the trigger.
• Customized Ergonomics and Optimal Eye Relief: Achieving the perfect eye relief is critical for comfort, safety, and performance. The extended multi-slot design grants you the freedom to position your scope precisely where it needs to be for your unique shooting style and body mechanics, maximizing your field of view and preventing uncomfortable neck strain or the risk of "scope bite" during recoil.
• Versatility for Every Mission: Whether you're upgrading to a new scope, adding a red dot for close-quarters engagements, or experimenting with different optic configurations, the Picatinny/Weaver compatibility ensures seamless transitions. This modularity means your rifle system can adapt to diverse shooting scenarios without requiring a complete overhaul of your mounting solution.
• Built to Endure the Toughest Conditions: From freezing mountain peaks to humid, swampy lowlands, the Weaver 99476's aerospace-grade aluminum construction and durable anodized finish ensure it stands up to the elements. Its resilience means your focus can remain on the shot, not on worrying about your equipment.
• Simplified, Secure Installation: Designed for a precise fit on the Winchester XPR Long Action, this one-piece base simplifies the mounting process. While professional installation is always recommended for critical components, the straightforward design allows for a secure and stable attachment, even for experienced DIY gun owners.
