The Marlin 336 is a classic lever-action rifle, beloved for its reliability and timeless design. However, its iron sights, while functional, might not suit every shooter or shooting situation. Adding a scope can significantly enhance accuracy and long-range shooting capabilities. But choosing and installing the right Marlin 336 scope mount requires careful consideration. This guide will walk you through the process, ensuring you make the best choice for your firearm and your needs.
Understanding Marlin 336 Receiver Variations
Before diving into scope mounts, it's crucial to understand that Marlin 336 rifles have seen variations in their receiver designs over the years. This impacts the type of scope mount you can use. Older models might require different solutions than newer ones. Key differences to consider include:
- Pre-64 vs. Post-64 Receivers: Pre-1964 Marlin 336s have a different receiver groove profile compared to post-1964 models. This makes using a universal mount unreliable. Always check your rifle's manufacturing date to confirm which type you have.
- Groove Depth and Width: Even within the pre- and post-64 categories, slight variations in receiver groove dimensions exist. This can impact the fit and stability of your scope mount.
Types of Marlin 336 Scope Mounts
Several types of mounts cater to the Marlin 336, each with its pros and cons:
1. Receiver Mounts:
- Advantages: These mounts directly attach to the receiver's grooves, providing a solid and stable base. Often the most preferred option for accuracy.
- Disadvantages: Requires careful selection to ensure a proper fit for your specific receiver type. Poor fitting can lead to damage. May require some gunsmithing for older models.
2. Side Mounts (Side-Rail Mounts):
- Advantages: These mounts attach to a rail installed on the side of the receiver. They offer a good solution for rifles where direct receiver mounting isn't feasible or ideal. They maintain a lower profile than some receiver mounts.
- Disadvantages: Can potentially shift the point of impact (POI) more than receiver mounts, requiring additional zeroing. Adding a side rail requires drilling and tapping the receiver, which should be done by a qualified gunsmith.
3. Scout Mounts:
- Advantages: Position the scope further forward, offering a good balance between eye relief and maintaining a comfortable shooting position. Ideal for lever actions.
- Disadvantages: Require a specialized mount and may interfere with the lever action in some cases.
Choosing the Right Marlin 336 Scope Mount
The ideal Marlin 336 scope mount depends on several factors:
- Receiver Type (Pre-64 or Post-64): This is paramount. Buy a mount specifically designed for your receiver type.
- Scope Size and Weight: A heavier scope requires a more robust mount capable of handling the added weight and recoil.
- Budget: Prices range from affordable to high-end. Consider your budget and the quality of materials you desire.
- Shooting Style and Intended Use: Consider how you'll be using the rifle. Long-range shooting might necessitate a more precise and stable mount than hunting at shorter ranges.
Installation of a Marlin 336 Scope Mount
While many mounts are designed for easy installation, professional installation is highly recommended, especially for those unfamiliar with firearms modifications. Incorrect installation can damage your rifle or compromise safety.
If you choose to install the mount yourself, follow these general steps:
- Carefully read the manufacturer's instructions. Each mount will have specific installation guidelines.
- Ensure proper alignment. Accuracy is critical. Use appropriate tools and take your time.
- Tighten screws evenly. Over-tightening can damage the mount or the receiver.
- Check for proper scope alignment. Ensure the scope is correctly aligned before zeroing.
Conclusion
Adding a scope to your Marlin 336 can enhance its versatility and accuracy. However, selecting and installing the right scope mount is crucial. Consider the factors outlined above, and if unsure, consult with a qualified gunsmith to ensure a safe and effective installation. Remember, safety and proper firearm handling always come first.
