The Mossberg 46B is a classic, reliable pump-action shotgun, prized for its simplicity and durability. However, its open sights can limit accuracy at longer ranges. That's where a scope mount comes in. This guide explores everything you need to know about finding and installing the right scope mount for your Mossberg 46B.
Understanding Your Mossberg 46B's Receiver
Before diving into scope mounts, understanding your shotgun's receiver is crucial. The Mossberg 46B's receiver is the main body of the gun, housing the action and the ejection port. The type of receiver you have dictates the type of scope mount that will work. While generally robust, variations exist over the years of production. Carefully examining your receiver will prevent purchasing an incompatible mount.
Types of Mossberg 46B Scope Mounts
Several types of scope mounts are available for the Mossberg 46B, each with its advantages and disadvantages:
1. Receiver Mounts:
These mounts attach directly to the receiver of the shotgun. They are generally considered the most secure and reliable option, offering a solid platform for your scope. However, ensure it’s designed specifically for the Mossberg 46B and its receiver variations. Improper installation can damage your firearm.
2. Picatinny Rail Mounts:
These mounts add a Picatinny rail to the shotgun's receiver. The advantage here is flexibility. You can attach various optics and accessories to the rail, beyond just a scope. However, this adds another layer of hardware, potentially introducing more points of potential failure.
3. Scope Bases:
These are the foundation of your mounting system, often attaching directly to the receiver and providing a platform for scope rings. Choosing a high-quality scope base is vital for accuracy and stability.
Factors to Consider When Choosing a Scope Mount
Several critical factors influence your choice of Mossberg 46B scope mount:
- Receiver Type: As mentioned earlier, the type of receiver on your shotgun will significantly limit your choices. Consult your owner’s manual or a qualified gunsmith if you're unsure.
- Scope Size and Weight: A heavy scope requires a robust mount to prevent sagging and potential zero shift. Consider the weight of your chosen optic and select a mount rated accordingly.
- Material: Steel is generally preferred for durability and stability. Aluminum offers a lighter alternative, but may be less robust for heavier scopes.
- Ease of Installation: Some mounts are easier to install than others. Consider your mechanical skills and choose a mount with clear instructions.
- Price: Prices vary significantly across brands and models. It’s worth investing in a quality mount that will last and ensure safe and reliable performance.
Installation Tips and Precautions
Installing a scope mount incorrectly can damage your firearm or compromise safety. Here are some critical tips:
- Consult the Instructions: Always follow the manufacturer's instructions carefully.
- Use the Correct Tools: Avoid using tools that could damage your firearm. Torque wrenches are recommended for many mounts.
- Proper Torque: Over-tightening can strip screws or damage the receiver. Under-tightening can lead to instability and potential failure.
- Seek Professional Help: If you're unsure about any aspect of the installation, seek help from a qualified gunsmith.
Conclusion
Choosing the right scope mount for your Mossberg 46B is crucial for maximizing accuracy and ensuring safe operation. Careful consideration of receiver type, scope weight, materials, and installation procedures will help you find the perfect mount for your needs. Remember, a properly installed and high-quality mount is an investment in your shooting experience and safety.
