The Marlin 336 is a legendary lever-action rifle, prized for its reliability, accuracy, and classic design. A seemingly small component, the rear band screw, plays a crucial role in the rifle's functionality and overall integrity. This guide delves into the importance of the Marlin 336 rear band screw, its function, potential issues, and how to address them.
Understanding the Marlin 336 Rear Band Screw's Function
The rear band screw, located at the rear of the receiver, secures the rear sight base and contributes to the overall stability and alignment of the rifle. It’s a critical part that shouldn't be overlooked during maintenance or repair. Its primary functions include:
- Securing the Rear Sight: The screw firmly holds the rear sight assembly in place, preventing movement or shifting during use. A loose screw can lead to inaccurate shots and inconsistent point of impact.
- Maintaining Receiver Integrity: While primarily supporting the rear sight, the screw contributes to the structural integrity of the receiver. A missing or damaged screw can compromise the receiver's stability.
- Preventing Damage: The rear band screw helps to prevent damage to the receiver and rear sight from recoil and impact.
Identifying the Rear Band Screw
The Marlin 333 rear band screw is typically a small, blued steel screw. It's easily identifiable by its location at the rear of the receiver, just below the rear sight. It’s usually a flathead screw, but variations may exist depending on the rifle's age and specific model.

Common Problems and Solutions Related to the Rear Band Screw
Several issues can arise with the Marlin 336 rear band screw, ranging from minor inconvenience to serious malfunctions. Let's examine some common problems and their solutions:
1. Loose Rear Band Screw
A loose screw is the most common problem. This often leads to:
- Shifting Rear Sight: The rear sight can move, causing inaccurate shots.
- Inconsistent Point of Impact: Shots may consistently land off-target.
Solution: Tighten the screw using the appropriate screwdriver. Avoid over-tightening, which can strip the screw or damage the receiver. If the screw is excessively loose, consider replacing it with a new one of the same size and type.
2. Stripped Screw Hole
Over-tightening or using the wrong screwdriver can easily strip the screw hole. This is a more serious issue requiring repair.
Solution: Options include:
- Helical Insert: Installing a helical insert is a durable and reliable solution, restoring the screw hole's integrity.
- Screw Repair Kit: Various screw repair kits are available which provide a stronger, more durable screw thread.
- Professional Gunsmith: A professional gunsmith can assess the damage and implement the most suitable repair.
3. Missing Rear Band Screw
A missing screw is a serious safety hazard and should be addressed immediately.
Solution: Replace the screw with an identical one. Improper replacement can compromise the firearm's safety and accuracy. It’s crucial to use a screw of the correct size and material to ensure proper function and stability.
Maintenance and Prevention
Regular maintenance is essential to prevent issues with the rear band screw and ensure the longevity of your Marlin 336.
- Regular Inspection: Inspect the screw for tightness during each cleaning and before each shooting session.
- Proper Tool Use: Always use the correct screwdriver to avoid stripping the screw.
- Avoid Over-Tightening: Tighten the screw firmly, but do not over-tighten.
- Lubrication: A small amount of gun oil applied to the screw threads can help prevent seizing.
Conclusion: The Importance of Proper Maintenance
The Marlin 336 rear band screw, while a small component, plays a crucial role in the rifle's accuracy and overall functionality. Regular inspection, proper maintenance, and prompt attention to any issues will ensure the continued reliable performance of your classic lever-action rifle. Remember, safety is paramount; if you are uncomfortable performing these tasks yourself, consult a qualified gunsmith.
