This article will explore the multifaceted world of the Mossberg 46b Scope Mount, offering practical insights and guidance to help you equip your vintage rifle with the precision of a contemporary scope.
Before delving into scope mounting solutions, it’s essential to understand the fundamental characteristics of the Mossberg 46b. These rifles typically featured a bolt-action mechanism known for its smooth operation and reliability. The original design almost always came equipped with iron sights, offering a traditional aiming experience. The sights typically consist of a blade front sight and an adjustable rear sight. This classic setup, while functional, has its limitations in terms of precision, especially at extended ranges or in less-than-ideal lighting conditions.
The receiver of the Mossberg 46b, the core structural component housing the bolt and firing mechanism, was not originally designed with scope mounting in mind. The receiver, therefore, typically lacks pre-drilled and tapped holes that are standard in modern rifles for attaching scope bases. This absence creates the primary hurdle for those wanting to add a scope to their Mossberg 46b and therefore requires the exploration of various modification and adaptation options.
Navigating the Challenges of Scope Mounting: Why It’s Difficult
The primary obstacle when scoping a Mossberg 46b is the absence of factory-installed mounting options. Unlike many later rifle designs that incorporate dovetailed grooves or pre-tapped holes for scope bases, the Mossberg 46b leaves you with very little to work with out-of-the-box. This situation requires more creativity and determination in order to succeed. This feature, or rather, lack thereof, means that mounting a scope is not as simple as bolting on a mount and attaching the rings. It often necessitates the utilization of specialized mounts and sometimes the modification of the rifle itself.
The receiver material, the shape of the action, and the historical context of the rifle’s design all contribute to the complexity of this task. Simply put, retrofitting a scope onto this classic rifle isn’t a straightforward process. However, the rewards – increased accuracy, improved target acquisition, and extended effective range – are significant enough to justify the effort.
Embracing the Alternatives: Exploring Scope Mounting Solutions
Fortunately, the community of gun enthusiasts and the aftermarket parts industry offer a range of solutions for the Mossberg 46b Scope Mount challenge. These alternatives cater to various skill levels and budgets, providing options for every owner.
The Permanent Solution: Drilling and Tapping the Receiver
One of the most secure and reliable methods for mounting a scope involves the drilling and tapping of the receiver. This process, which involves creating threaded holes in the receiver to accept scope mount screws, permanently alters the rifle. It is a relatively involved process that generally demands a gunsmith’s expertise. A qualified gunsmith can accurately drill and tap the receiver, ensuring a secure and aligned mounting surface for your chosen scope base.
The advantage of this method is clear: it provides the most robust and stable platform for your scope. The permanent nature of the modification, however, should be considered. Once the receiver is drilled and tapped, it cannot be easily reversed. This factor can affect the value of the rifle for collectors and can be a concern for those wanting to maintain their firearm’s original condition.
Claw-Style Mounts: A Less-Permanent Option
Claw-style mounts offer an alternative that avoids permanent modification. These mounts typically clamp onto the receiver, often using friction or a combination of clamps and screws to secure the scope base. They provide a more temporary solution, allowing for easier removal and reinstallation of the scope.
While potentially less intrusive than drilling and tapping, claw-style mounts can have limitations. Depending on the design and quality, they might not offer the same level of stability as a drilled and tapped mount. In addition, there is a potential risk of marring or damaging the receiver’s finish, so it is important to select high-quality mounts with appropriate padding or protective features. Careful installation and regular checks for tightness are crucial when using claw-style mounts to ensure both accuracy and safety.
Aftermarket Bases: Leveraging Modern Engineering
The aftermarket industry is a critical resource for the Mossberg 46b Scope Mount endeavor. Various companies specialize in producing scope mount bases designed specifically for this rifle model or adaptable to its design. These bases often utilize standard mounting patterns, such as Weaver or Picatinny rails, allowing for a wide range of scope ring options.
When exploring aftermarket bases, research the available choices thoroughly. Look for bases that are made from durable materials, like steel or high-grade aluminum, for strength and longevity. Check customer reviews and consider the ease of installation, ensuring the mount is compatible with your chosen scope and rings. Some bases may come with detailed instructions, while others might require a bit more mechanical aptitude. The range of available options is always changing, so constant diligence in researching what is available on the market is required.
Adapting What’s Available: Creative Solutions
Those with a knack for innovation and a willingness to experiment may explore adapting existing mounts for use on the Mossberg 46b. This could involve utilizing mounts from other rifle models, modifying existing parts, or combining different components. This approach may require a degree of mechanical skill, but it can often lead to a cost-effective and personalized solution. This might, for example, involve using scope rings designed for a Weaver rail and attaching them to a customized base or modified base.
Always prioritize safety and accuracy when attempting such modifications. Ensure that any adaptations do not compromise the rifle’s functionality or structural integrity. Consult with a gunsmith if you have any doubts about the feasibility or safety of your project.
Choosing the Right Scope: Matching Optics to Your Rifle
Selecting the appropriate scope is as important as choosing the right Mossberg 46b Scope Mount. The scope’s specifications, including magnification, objective lens size, and reticle type, should align with your intended use for the rifle.
For a Mossberg 46b, a rimfire-specific scope is often a good choice. These scopes are generally designed to withstand the relatively low recoil of .22 rimfire cartridges. A magnification range of 3-9x or similar is generally suitable, offering versatility for various shooting distances. The objective lens size, which influences light gathering capability, should be chosen with consideration for the size and weight of the scope.
The reticle, or aiming pattern, is another critical factor. Simple crosshairs are a common choice, while more complex reticles with range-finding features can enhance accuracy at longer distances. The type of reticle and magnification combination will significantly impact the user’s accuracy capabilities.
Your budget is a critical factor in scope selection, as it significantly limits your options. High-quality scopes provide superior clarity, light transmission, and durability, but are typically accompanied by higher prices.
Mastering the Installation: Steps to Success
Once you’ve chosen your scope and mount, it’s time for installation. This process requires care and precision to ensure accurate results.
First, prepare your rifle and mount. Clean the receiver and the mount surfaces to remove any debris or oil. Read the manufacturer’s instructions carefully. Gather the necessary tools, including a torque wrench, screwdrivers of the correct size, and potentially a level.
If using a base, securely attach it to the receiver following the manufacturer’s instructions. Use the correct torque settings for the screws to prevent damage. Attach the scope rings to the base, ensuring they are correctly aligned. Place the scope in the rings and tighten them gradually, alternating between the screws to maintain even pressure.
During the process, make sure the scope is level and aligned with the rifle’s bore axis. This may require the use of leveling tools or a simple eye-balling technique. Proper alignment will contribute greatly to the accuracy of the scope.
