Understanding the Zastava M77 and Basic Scope Mounting Principles
Overview of the Zastava M77
The Zastava M77, a robust and reliable rifle, has earned its place as a favorite among enthusiasts who appreciate its powerful chambering in 7.62x51mm NATO. Known for its AK-based design and inherent ruggedness, the M77 offers impressive performance, but its capabilities are significantly enhanced with the addition of a quality scope. However, the right Zastava M77 scope mount is absolutely critical. This guide explores the ins and outs of selecting, installing, and maintaining the perfect scope mount for your M77, ensuring that you get the most out of your rifle.
With its inherent accuracy, the M77 excels with a well-mounted optic. However, the AK-style platform presents a specific set of challenges when it comes to scope mounting. Unlike some modern rifles with integrated Picatinny rails, the M77’s design requires thoughtful consideration to ensure a secure and stable platform for your chosen optic. This is where a proper Zastava M77 scope mount becomes essential.
Why Use a Scope?
Why even bother with a scope? Simply put, a scope dramatically enhances the rifle’s capabilities. A scope amplifies the target, making it easier to acquire and engage at extended ranges. It improves accuracy by providing a stable, magnified view and allowing for precise aiming. Using a scope also allows you to compensate for factors like bullet drop and wind drift, leading to more consistent shot placement. Choosing the right scope is important, but without a solid, reliable mount, the scope is useless. The benefits are clear: improved accuracy, extended range, and better overall shooting performance.
Scope Mounting Fundamentals
Before diving into the different types of mounts, it’s essential to understand the fundamentals of scope mounting. The goal is to create a stable, secure, and repeatable platform that allows the scope to function correctly. Key factors to consider include the following:
- Stability: The mount must be able to withstand the recoil of the rifle without shifting or loosening.
- Durability: The mount should be made of high-quality materials and be able to withstand the rigors of use in various conditions.
- Eye Relief: Proper eye relief is critical for comfortable and accurate shooting. This is the distance between your eye and the scope’s eyepiece that provides a full field of view.
- Mount Height: The height of the mount should be appropriate for your shooting style and desired cheek weld.
- Return to Zero: The mount should be able to be removed and reattached without significantly altering the scope’s zero.
- Installation: Proper installation is crucial. Follow the manufacturer’s instructions carefully.
Types of Zastava M77 Scope Mounts
Side Mounts
One of the most common solutions is the side mount. These mounts attach to the receiver via a specialized side rail. This rail is either integrated into the receiver during manufacturing or, in some cases, can be added. The benefit of a side mount is its high level of stability. Many side mounts are known for excellent return-to-zero capabilities, allowing you to remove and reattach the scope without significant adjustment. They are often made of steel or high-quality aluminum. The disadvantage is that side mounts often add a bit of bulk to the rifle. Also, depending on the specific side mount and scope combination, you may need to consider the position of the charging handle for clearance. Brands like Midwest Industries and RS Regulate are well-regarded for producing high-quality Zastava M77 scope mounts of this type.
Top-Cover Rails
Another popular choice involves top-cover rails. These rails are designed to replace the standard dust cover of the M77. They offer a potentially lighter profile than side mounts, but they can present some challenges. The top cover itself isn’t usually designed to be the most stable mounting platform. Zero retention may be less consistent compared to side mounts, and the top cover is subject to significant vibration during firing. Some models address this by having additional locking mechanisms or incorporating reinforced designs. While some of these can perform well, it’s vital to choose a top-cover rail with a solid reputation for stability. Companies such as UTG and Tactical Tailor offer these types of mounts, but buyer beware: always research reviews and choose one that has a reputation for reliability.
Receiver-Mounted Rails
Finally, there are options for receiver-mounted rails. This generally involves permanently modifying the receiver by drilling and tapping holes to attach a Picatinny rail. This is a very stable and reliable option as the rail is directly connected to the most solid part of the rifle. It can provide excellent zero retention. However, it’s a permanent modification and should only be undertaken by a qualified gunsmith if you don’t have the experience and the proper tools. This approach requires careful consideration and a full understanding of the implications.
Other Mount Options
Other options may include mounts specifically made for a particular scope, although these are less common for the M77, since it’s not a platform known for very niche customizations. Regardless of which type you choose, consider how well it fits your needs and shooting style.
Choosing the Right Scope Mount for Your Zastava M77
Factors to Consider
Choosing the best Zastava M77 scope mount requires careful consideration. Your specific needs will influence the optimal choice.
- Intended Use: Are you hunting, participating in tactical competitions, or just target shooting? The intended use of the rifle is one of the most important factors to consider. A hunter may prioritize a lightweight mount and a lower profile, while a competitive shooter may prioritize maximum stability and return-to-zero capabilities.
- Budget: Scope mounts range in price. Determine how much you can spend on the mount. Remember to allocate sufficient funds for a quality mount; it directly impacts the performance of your chosen optic.
- Scope Selection: The scope you choose will play a big role in the mount you require. Ensure that the mount you select is compatible with your scope’s tube diameter and overall design.
- Durability: Does the mount need to withstand rough handling and harsh environments? Choose a mount made from high-quality materials like steel or aircraft-grade aluminum.
- Eye Relief: Ensure the mount allows for comfortable eye relief, as this will make for a more comfortable and precise shooting experience.
- Ease of Installation: If you prefer to install the mount yourself, choose a model with clear instructions and an easy-to-use design. If you are not confident in your ability to install the mount, seek the help of a gunsmith.
Evaluating Mount Features
Evaluating a scope mount involves examining several features. Here are some key aspects:
- Materials: High-quality mounts are usually made of aluminum alloys or steel, providing strength and durability.
- Mounting Hardware: Ensure the mount includes quality screws, bolts, and attachment mechanisms.
- Adjustment Mechanisms: Some mounts offer adjustments for windage and elevation or the ability to adjust for cant. Consider these features if they are beneficial to your shooting style.
- Return-to-Zero Capabilities: Look for a mount known for its ability to maintain zero after being removed and reattached.
- Design and Build Quality: Examine the fit and finish of the mount, and consider user reviews to gauge overall quality.
Installation and Zeroing
Step-by-Step Installation Guide
Once you have your chosen Zastava M77 scope mount, follow these steps to install and zero your scope correctly.
Start with a clean and safe workspace. Gather the necessary tools, including the scope mount, scope, mounting hardware (if not pre-assembled), a torque wrench, and any tools specified by the mount manufacturer.
If you have a side mount, the specific installation steps will vary depending on the model. Generally, you’ll need to ensure that the rail interfaces with the receiver properly. Consult the manufacturer’s instructions, but typically, this will involve attaching the mount base to the receiver’s side rail with bolts or screws, followed by mounting the scope rings to the base rail. Tighten screws to the manufacturer’s specifications using a torque wrench to prevent damage to the mount or the rifle.
If you’re using a top-cover rail, you’ll remove the existing dust cover. The installation will vary from model to model. Some will clip into the existing hinge, while others may require modifications. Make sure the rail is securely attached and that the charging handle operates freely.
Attach the scope rings to the mount. Make sure the scope rings are properly spaced to accommodate the scope’s tube diameter. Then, place the scope in the rings and carefully tighten the screws on the rings, ensuring that the scope is level. Again, consult the manufacturer’s instructions for proper torque specifications.
Zeroing the Scope
Once the mount and scope are installed, it’s time to zero the scope. This involves adjusting the scope’s reticle to align with the point of impact of your bullets at a specific distance.
Begin by setting up a target at a known distance. Use a stable shooting position. Fire a three-shot group. Observe where the shots hit on the target. Then, use the scope’s windage and elevation adjustments to move the reticle to align with your point of impact.
Typically, a scope has two adjustment turrets, one for elevation (up and down) and one for windage (left and right). Adjust these turrets, making small adjustments, and shoot another group. Repeat this process until your shots are impacting where you want them to.
Maintenance and Troubleshooting
Cleaning and Maintenance
Proper maintenance will help extend the life of your Zastava M77 scope mount and ensure continued optimal performance.
Regularly inspect your mount and scope for any signs of damage or loosening. Clean the mount and scope regularly, using a soft cloth. Periodically check and re-tighten screws and bolts to ensure they remain secure.
Troubleshooting Common Issues
If you encounter issues, consider these troubleshooting tips:
- Loose Mount: Check and tighten any screws or bolts. If the mount continues to loosen, consider replacing it or using thread locker.
- Zero Shifts: If your zero is shifting, check the mount and rings for any movement. Ensure that the scope is securely mounted.
- Improper Adjustments: Ensure you understand how to use the scope’s windage and elevation adjustments. Refer to the scope’s manual for specific instructions.
