While the rifle itself is a testament to American craftsmanship, its full potential for precision and consistent accuracy is unlocked with the right optical setup. This begins not with the scope, but with the rock-solid connection between your rifle and its aiming device: the scope base.

When considering an upgrade or new build for your Winchester Model 70A Long Action, questions naturally arise: "What is the best scope base for my Winchester 70A?" or "How can I ensure my riflescope maintains its zero even in harsh conditions?" The answer for many experienced shooters points directly to the Redfield 513112 1-Piece JR Base in a stealthy Matte Black Finish. This specific base is engineered to solve the critical problem of providing an unyielding, perfectly aligned platform for your optics, ensuring that every shot counts, whether in the field or on the range.

Understanding the Redfield 513112 JR 1-Piece Scope Base

The Redfield 513112 1-Piece JR Base isn't just another accessory; it's a precision-engineered foundation. Designed specifically for the Winchester Model 70A Long Action rifles, this base is a single, continuous piece of high-grade material. This monolithic design offers distinct advantages over traditional two-piece bases, which we'll explore in detail.

At its core, a scope base provides the interface between your rifle's receiver and your chosen scope rings, which in turn hold your riflescope. The integrity of this connection is paramount. Any flex, misalignment, or instability in the base can translate directly into lost accuracy, frustrating shifts in point of impact, and a general lack of confidence in your setup. The Redfield 513112 JR Base is purpose-built to eliminate these concerns, delivering a stable and reliable platform from the first shot to the last.

The Matte Black Finish of the Redfield 513112 base is more than just aesthetic; it’s functional. This non-reflective coating minimizes glare and reflections, crucial for hunters who need to remain unseen and unhindered by bright light conditions. It also offers excellent corrosion resistance, protecting the base from the elements and ensuring its longevity, whether you're braving damp forests or dusty plains.

Why a 1-Piece Scope Base is a Superior Choice

For many shooters, the decision between a 1-piece and a 2-piece scope base is critical. The Redfield 513112 embraces the 1-piece design, and for good reason. A single-piece base spans the entire length of the rifle's receiver, offering several key benefits that directly contribute to enhanced shooting performance:

• Unrivaled Rigidity and Strength: By integrating the mounting points into a single unit, the 1-piece base inherently possesses superior rigidity. This means less potential for flex or torsion under recoil or stress, maintaining the precise alignment of your scope rings and, consequently, your riflescope. For powerful cartridges often chambered in the Winchester Model 70A Long Action, this added strength is invaluable.
• Enhanced Scope Ring Alignment: One of the most significant advantages of a 1-piece design like the Redfield 513112 is the improved alignment between the front and rear scope rings. Because they are mounted on a single, precisely machined rail, the likelihood of misalignment is drastically reduced. Proper ring alignment prevents binding of the scope tube, which can introduce stress on the scope's internal components, potentially damaging it or affecting its tracking and zero. A well-aligned base ensures your scope functions as intended, delivering optimal optical performance and preserving its lifespan.
• Reduced Stress on Optics: When a scope tube is forced into misaligned rings, it can lead to crimping or internal component damage. A 1-piece base provides a much more uniform and stress-free mounting surface, allowing the scope to sit naturally and securely. This contributes to the long-term durability and reliability of your expensive optics.
• Simplified Installation: While two-piece bases require precise alignment of two separate components, a 1-piece base simplifies the initial mounting process. Once the base is securely attached to the receiver, the rings can be mounted and aligned with greater ease, leading to a quicker and more accurate setup.

Precision Fit: The Winchester Model 70A Long Action

The compatibility of the Redfield 513112 JR Base with the Winchester Model 70A Long Action is not an afterthought; it's a fundamental design consideration. Winchester's Model 70 rifles are renowned for their "Controlled Round Feed" system and robust actions, trusted by generations of hunters and competitive shooters. The "Long Action" designation refers to the specific receiver length designed to accommodate longer cartridges, such as the .30-06 Springfield, .270 Winchester, 7mm Rem Mag, and .300 Win Mag.

The Redfield 513112 base is meticulously designed to match the receiver contours and screw hole patterns of these long-action rifles. This precise fit ensures:

• Optimal Bore Alignment: The base sits perfectly flush with the receiver, providing an ideal mounting surface directly over the rifle's bore. This minimizes the need for excessive windage or elevation adjustments on your scope, allowing its internal mechanisms to operate closer to their optical center.
• Maximum Contact for Stability: A perfect fit means maximum surface area contact between the base and the receiver, leading to superior clamping force and preventing any movement of the base under recoil or impact. This "no-slip" guarantee is critical for maintaining zero, especially in demanding environments.
• Seamless Integration: When installed, the Redfield 513112 looks like a natural extension of the Winchester Model 70A, maintaining the rifle's clean lines while providing robust functionality.

Answering Your Questions: Choosing and Installing Your Scope Base

"How do I choose the right scope base for my Winchester 70A?" The most critical factor is exact model compatibility. The Redfield 513112 is explicitly designed for the Winchester Model 70A Long Action. Always verify your rifle's specific model and action length before purchasing. The choice between 1-piece and 2-piece should lean towards 1-piece for maximum stability and alignment, as offered by this Redfield base.

"What tools do I need to mount a scope base?" Basic tools typically include a set of screwdrivers with appropriate bits (often Torx or hex), a torque wrench (crucial for proper screw tension), and potentially a leveling kit for scope alignment. Some gunsmiths also recommend a lapping tool for scope rings, though with a high-quality 1-piece base like the Redfield 513112, this step is often less critical due to the inherent alignment.

"How does a quality scope base improve shooting?" A quality base eliminates movement between the rifle and the scope. If the base shifts even microscopically, your point of impact will shift. A stable base, combined with properly installed rings, ensures that every time the rifle recoils, the scope returns to the exact same position relative to the bore, leading to consistent accuracy and reliable zero.

"Is a Redfield base reliable?" Redfield has a long-standing history, dating back to 1909, of producing robust and dependable shooting accessories. Their JR bases are a testament to this legacy, known for their durable construction and precise fit. When properly installed, a Redfield 513112 base is engineered to be a highly reliable component of your rifle system.

Installation Tips for Optimal Performance

While installing a scope base might seem straightforward, following best practices ensures maximum performance from your Redfield 513112 JR Base.

1. Clean Surfaces Thoroughly: Before installation, ensure the top of your rifle's receiver and the underside of the scope base are meticulously clean and free of oil, grease, or debris. Use a degreaser if necessary.
2. Use Blue Threadlocker: Apply a small amount of non-permanent (blue) threadlocker to the base screws before tightening. This prevents screws from backing out due to recoil and vibration. Do NOT use red threadlocker, as it may make future removal extremely difficult.
3. Torque Screws to Spec: This is arguably the most crucial step. Consult your rifle's manual or the base's instructions for the recommended torque specifications for the base screws. Using a quality torque wrench is essential. Overtightening can strip screws or warp the receiver; undertightening can lead to a loose base.
4. Check for Proper Fit: After tightening, visually inspect the base to ensure it sits flush against the receiver with no gaps or rocking.
5. Level Your Scope: Once the base is installed, use a leveling tool to ensure your scope rings (and subsequently, your scope) are perfectly level. This prevents canting, which can introduce windage errors at long range.

Following these steps will help you achieve the rock-solid platform that the Redfield 513112 base is designed to provide, maximizing your rifle's accuracy potential.
