Understanding Scope Bases: Function and Purpose
Basics & Functions
A scope base is the foundational element used to attach a telescopic sight, or scope, to the rifle’s receiver. It’s a seemingly simple component, but its function is profound, directly impacting the shooter’s accuracy and the scope’s functionality.
At its core, the scope base provides a stable, secure platform on which the scope rings can be mounted. The primary purpose of the scope base is to ensure that the scope sits correctly relative to the bore of the rifle. This establishes the initial zero, the point at which the scope and the bullet’s trajectory align at a specific distance. The alignment afforded by the base is critical because any misalignment leads to inaccuracies, making it difficult to consistently hit the target.
The scope base must also be robust enough to withstand the recoil generated when the rifle is fired. This can be a significant force, especially with larger calibers. If the base is not built to handle the recoil, it could shift or loosen, causing the scope to lose its zero, requiring constant adjustments and frustrating the shooter.
The design of the base also facilitates adjustments. Scope bases come in various heights and configurations, allowing the shooter to position the scope at an appropriate height for comfortable and effective use. This is especially important for achieving a proper cheek weld, the position of the shooter’s cheek against the stock, which affects how the eye lines up with the scope’s lenses.
The connection between the scope base and the rings is of paramount importance. The rings themselves are what ultimately hold the scope. The base sets the stage, establishing the platform on which the rings attach. It is crucial that the base and rings work in harmony, creating a secure and aligned system for the scope.
Types of Remington 700 Scope Bases
One-Piece Scope Bases
One-piece scope bases are known for their exceptional rigidity and overall stability. They are crafted as a single unit, which minimizes the points of potential failure or misalignment. This design generally offers a more secure platform for the scope, making it a popular choice for long-range shooting and applications where consistent accuracy is crucial.
One-piece bases are generally made from high-quality steel or aluminum. Steel is known for its remarkable durability and resistance to wear, providing a robust platform, even under the harshest conditions. However, steel bases can add noticeable weight to the rifle, a consideration for some shooters. Aluminum offers an excellent balance of strength and lightweight characteristics, making it a popular option for hunters who prioritize minimizing the overall weight of their equipment.
Installation of a one-piece base demands precision. Correct installation requires careful attention to detail. The receiver must be thoroughly cleaned before mounting, removing any dirt or debris that could interfere with proper seating. Ensuring the base is level is essential. The base will provide the base from which your adjustments and holdovers will be determined. Finally, using the correct torque specifications when tightening the screws is critical to prevent over-tightening or loosening of the base, and threadlocker compounds can enhance the security of the screws, protecting them from the vibration generated by the firing process.
Two-Piece Scope Bases
Two-piece scope bases provide flexibility in adjustment. With separate front and rear bases, the shooter can customize the position of the scope to optimize eye relief and adjust for different rifles or user preferences. This can be particularly useful for shooters who require a specific eye relief for comfortable and accurate shooting.
These bases are also often made of steel or aluminum, offering similar benefits in terms of durability and weight. They also offer the benefit of being lighter weight than a one-piece base.
The alignment of the two pieces is vital. The rings need to be aligned to be correct. The individual base pieces must be parallel to each other. Misalignment, however small, can put stress on the scope tube and potentially cause issues over time. Careful alignment of the bases during installation is crucial.
Rail Systems
Rail systems represent an increasingly popular option.
Picatinny rails are the military standard and one of the most widely adopted rail systems in the shooting community. Known for their versatility and standardization, Picatinny rails are easily recognized by their series of precisely spaced slots, which allow for a wide range of accessories, including scopes, to be attached. This design ensures that accessories can be readily mounted and dismounted and remain consistent, regardless of the manufacturer. The Picatinny rail’s standardized nature makes it a reliable and adaptable choice for the Remington 700.
Weaver rails represent an older standard. While not as prevalent as Picatinny rails, Weaver rails also provide a mounting platform for scopes and accessories. The distinguishing feature of a Weaver rail is its wider, less precise slot spacing. While they are still commonly used, they may not offer the same level of compatibility with all accessories, particularly those designed for Picatinny rails.
Both Picatinny and Weaver rails offer their own advantages and disadvantages. The Picatinny rail, with its standardization and precise slot spacing, offers greater compatibility and a higher level of customization. Weaver rails, however, can sometimes be more affordable and may still be suitable for certain applications.
Key Considerations When Choosing a Scope Base
Material
The material from which the base is constructed is a primary consideration. Steel, known for its strength and durability, offers a robust platform that can withstand the rigors of repeated use. The steel is a great platform, but can add additional weight. Aluminum provides a lighter-weight alternative, making it easier to carry the rifle for extended periods. The material will affect how the base responds to recoil.
Construction
The quality of the construction is crucial. This encompasses the machining quality of the base, the precision with which it is manufactured, and the overall finish of the base. The quality of the machining will affect the alignment and durability. A precisely machined base will provide a more accurate and reliable platform. The finish will impact the base’s longevity and aesthetic appearance. High-quality finishes protect the base from the elements, preventing corrosion and ensuring its continued functionality.
Compatibility
Compatibility between the base and other components is also crucial. Consider the size of the scope tube and select a base that can accommodate the tube’s diameter. It’s important to verify that the base is the right size for the rifle. This verification should occur before any installation.
Eye Relief and Mounting Position
Consider the desired eye relief, or the distance between the shooter’s eye and the scope’s eyepiece that provides a full field of view. The mounting position of the scope on the base is crucial to ensure the correct eye relief. The goal is to find a position that provides a comfortable and clear view of the target while allowing for proper cheek weld and comfortable shooting. The height of the base may be crucial for getting a proper eye relief.
Budget
Setting a budget for a Remington 700 scope base is a practical necessity. Scope bases vary in price based on their materials, design, brand, and features. Carefully assess the quality, features, and your needs, and then determine a reasonable price range.
Installation and Maintenance
Installation
The receiver should be free of any debris. Begin by carefully cleaning the receiver of the rifle, using a solvent or specialized cleaning solution to remove any oil, grease, or debris that could interfere with proper contact.
Next, mount the scope base on the receiver. Carefully align the base with the pre-drilled holes on the receiver and insert the mounting screws. Ensuring a level base is crucial for achieving optimal accuracy. Check the level of the base before proceeding. If a level is available, be sure to use it.
Apply the correct torque. The torque specifications are often provided by the base manufacturer, and adhering to these guidelines is essential to prevent over-tightening, which could damage the base or receiver threads, or under-tightening, which could lead to loosening and loss of zero.
Applying threadlocker to the screws adds another layer of security, ensuring they remain securely fastened, even during heavy recoil. Threadlocker helps to prevent loosening and protects the screws from the impact of the vibrations.
Maintenance
Regular maintenance ensures the base and the mounted scope continue to function properly.
Regular inspection involves checking all the screws for tightness. Before each shooting session, carefully examine the screws holding the base to the receiver and the scope rings to the base to ensure they are securely fastened. If they are loose, tighten them immediately.
Keep the base clean by wiping it down periodically. Remove any dust, dirt, or debris that may accumulate on the base.
Troubleshooting
If problems arise, it is important to understand how to solve them. A base not level may occur. If this happens, it may require shimming the base or using adjustable rings to address the issue. In some cases, the scope may move during recoil. A common problem, and can be caused by several factors, including loose screws, insufficient torque, or a damaged base. Tightening the screws, using threadlocker, or replacing the base may resolve this issue.
Conclusion
Choosing the appropriate Remington 700 scope base is a fundamental step in maximizing the rifle’s performance. The decision is an investment in your ability to shoot accurately and consistently. Selecting a base that complements your scope, fits the rifle, and aligns with your shooting goals is key to success.
Be sure to take the time to research, consider the available options, and invest in a high-quality base that meets your needs. The right choice will make all the difference.
