The Ultimate Foundation for Precision: Weaver 99502 Multi-Slot 20 MOA Base for Remington 700 Long Action

For the dedicated long-range shooter, the precision hunter, or the competitive marksman who demands unwavering accuracy, the foundational element of any reliable optical system begins with the scope base. Among the myriad choices, the Weaver 99502 Multi-Slot Extended Base, specifically engineered for the iconic Remington 700 Long Action rifles, stands out as a critical component designed to unlock the full potential of your firearm and optics. This isn't just a piece of metal; it's a meticulously crafted interface that bridges your rifle with your scope, ensuring perfect alignment and providing the essential cant needed for extreme distance shooting.

If you’re asking questions like, "What is the best scope base for long-range shooting with a Remington 700?", "How can I get more elevation travel from my rifle scope?", or "Why do I need a 20 MOA base for my .30-06 or .300 Win Mag?", then understanding the unique advantages of the Weaver 99502 is paramount. This base directly addresses the inherent challenges of gravity on a bullet's trajectory, allowing shooters to effectively zero their scopes and maintain vital internal elevation adjustments for shots out to hundreds, even thousands, of yards.

Why Choose a 20 MOA Scope Base? Overcoming Ballistic Drop

One of the most profound benefits of the Weaver 99502 is its integrated 20 Minute of Angle (MOA) cant. But what exactly does 20 MOA mean for your shooting experience? In simple terms, a 20 MOA base is slightly tapered, raising the rear of your scope relative to the front. This slight downward tilt of your scope (relative to the bore) effectively "pre-loads" your scope's internal elevation adjustment.

Consider this: as a bullet travels downrange, gravity constantly pulls it towards the earth, causing it to drop. To compensate for this drop, you adjust your scope's elevation turret, moving the reticle up to match the bullet's impact point. Standard (0 MOA or "flat") bases typically require significant upward adjustments for long-range shots. Your scope has a finite amount of internal elevation travel. If you're shooting at extreme distances, you might exhaust your scope's internal adjustment range before you can zero for the desired distance, or you might find yourself with very little "up" adjustment left for even longer shots.

A 20 MOA base solves this by providing a fixed "down" compensation from the start. This means your scope's erector system starts closer to the bottom of its adjustment range, leaving significantly more "up" adjustment available for dialing in those distant targets. For a typical scope, a 20 MOA base can add hundreds of yards of effective shooting range without requiring holdovers or expensive custom reticles. This is particularly crucial for cartridges commonly chambered in Remington 700 Long Action rifles, such as .30-06 Springfield, .270 Winchester, 7mm Remington Magnum, .300 Winchester Magnum, and .338 Lapua Magnum, which are frequently pushed to their ballistic limits.

Precision Engineered for Remington 700 Long Action

The Weaver 99502 is not a one-size-fits-all solution; it is meticulously designed for the specific contours and screw patterns of the Remington 700 Long Action. This precise fit ensures maximum surface contact between the base and the receiver, leading to superior rigidity and stability. A stable base is paramount for maintaining zero, especially under recoil or during repeated handling. An ill-fitting base can lead to subtle shifts, throwing off your point of impact and leading to frustrating missed shots.

The Remington 700 Long Action is renowned for its robust design and accuracy potential, making it a popular choice for everything from big game hunting to competitive long-range precision. This Weaver base complements the rifle's inherent strengths, providing a rock-solid platform for your chosen optics. Whether you're upgrading an existing rifle or building a new long-range setup, selecting a base specifically tailored to your rifle's action length is a non-negotiable step for optimal performance.

Multi-Slot Design: Unparalleled Versatility

The "Multi-Slot" aspect of the Weaver 99502 refers to its full-length Picatinny (MIL-STD-1913) rail interface. This universal design offers unmatched versatility for mounting your scope rings and other accessories. Unlike two-piece bases or proprietary mounting systems, a Picatinny rail provides:

• Flexible Ring Placement: You can position your scope rings anywhere along the base's length, allowing for optimal eye relief adjustment regardless of your scope's tube length or your shooting position. This is a significant advantage for shooters who use variable power scopes or those who want to fine-tune their setup for comfort and rapid target acquisition.
• Compatibility: The Picatinny standard is the most widely adopted mounting interface in the firearms industry. This means the Weaver 99502 is compatible with virtually any Picatinny or Weaver-style scope rings, giving you a vast selection of options from various manufacturers.
• Repeatability: When you remove and reattach your scope, a high-quality Picatinny base and rings system offers excellent return-to-zero capabilities, meaning less time spent re-zeroing your rifle.

This robust and adaptable design ensures that your optics are securely mounted, providing a stable foundation for consistent accuracy shot after shot.

Durable Construction and Finish

Crafted from high-grade aluminum, the Weaver 99502 Multi-Slot Base is engineered for lightweight strength and long-lasting durability. Aluminum is an ideal material for scope bases due to its excellent strength-to-weight ratio, which adds minimal bulk to your rifle while providing robust support for your optics. The base undergoes a black anodized finish process, which serves multiple purposes:

• Corrosion Resistance: The anodized layer creates a hard, protective surface that is highly resistant to corrosion, scratches, and wear from environmental exposure. This is crucial for bases that will be subjected to varying weather conditions in the field.
• Non-Reflective Surface: The matte black finish reduces glare and reflections, which is important for maintaining a low profile in hunting scenarios or preventing optical interference during competitive shooting.
• Aesthetics: The sleek black finish seamlessly integrates with most rifle and scope setups, providing a professional and refined appearance.

This combination of material and finish ensures that your Weaver base will stand up to the rigors of recoil, field use, and extreme temperatures, maintaining its integrity and performance over years of service.

Installation and Setup Considerations

While the Weaver 99502 is designed for straightforward installation, proper mounting is critical for achieving optimal accuracy. Here are some general considerations, though specific rifle and scope ring instructions should always be followed:

1. Cleanliness: Ensure your rifle's receiver screw holes and the base's mating surface are free of any oil, grease, or debris. A clean surface promotes a secure fit and proper thread locking.
2. Screw Preparation: Apply a small amount of a non-permanent thread locker (like Loctite Blue 242) to the base screws. This prevents screws from loosening under recoil, which can cause point of impact shifts.
3. Torque Settings: Use a quality torque wrench to tighten the base screws to the manufacturer's recommended specifications. Over-tightening can strip threads or deform the base, while under-tightening can lead to instability.
4. Leveling: Once the base is securely mounted, ensure your scope is perfectly level within the rings before tightening them. A canted reticle can lead to significant errors at long range.

Investing in proper tools and taking your time during installation will ensure that the Weaver 99502 performs as intended, providing a stable and reliable platform for your valuable optics. For those less confident in performing the installation themselves, seeking assistance from a qualified gunsmith is always a wise decision.
