Understanding the A2 Rear Sight
Features and Function
The A2 rear sight, often referred to as the “carry handle” sight in its integrated form, is a classic design. It provides a robust and reliable aiming solution. Its core function is to work in conjunction with the front sight post, forming the basis of a precise sight picture. The A2 features two primary adjustable elements: elevation and windage. Elevation adjustments compensate for bullet drop over distance, while windage adjusts for the bullet’s drift caused by wind or other factors. Most A2 sights also incorporate two apertures – a smaller, more precise aperture for longer ranges and a larger, quicker-acquisition aperture for close-quarters scenarios.
Importance in Aiming
The design’s simplicity contributes to its durability and ease of use. The sight is typically crafted from durable steel or aluminum alloys, ensuring it can withstand the rigors of regular use and the recoil generated by firing. The sight picture itself is straightforward: align the front sight post within the rear aperture, and center the target. This method, properly executed, delivers remarkably accurate results at varying distances. There are different methods used to install the rear sight and the best is to utilize a specific tool.
Different Installation Methods
The different installation methods can vary, but the most effective and reliable method is utilizing the proper tool for the task.
Why You Need an A2 Rear Sight Installation Tool
Challenges Without the Right Tools
Attempting to install an *A2 Rear Sight Installation Tool* without the proper equipment is a recipe for frustration and potential damage. The sight must be seated squarely and firmly into its base to function correctly. Using improvised tools like punches, hammers, or even less appropriate items drastically increases the risk of damaging the sight, the rifle’s receiver, or both. Applying uneven pressure can cause the sight to sit crooked, rendering it ineffective and frustrating to zero.
Benefits of Using the Tool
The correct tool provides the most reliable means to mount your rear sight assembly. Here’s why you need to utilize an *A2 Rear Sight Installation Tool*:
Even and Secure Installation: The tool ensures the sight is pressed into place uniformly, avoiding stress points that can lead to deformation or misalignment.
Prevents Damage: By distributing force correctly, the tool minimizes the risk of scratching, bending, or otherwise marring the sight or the rifle’s receiver.
Speed and Efficiency: The specialized design allows for a quicker and easier installation process compared to makeshift methods. What might take you an hour using a hammer and a punch, could take you a matter of minutes with the proper tool.
Comparison to Other Methods
The benefits are clear. The installation tool eliminates the guesswork and the potential for costly mistakes. Using the right tool gives the user confidence in knowing that the process is done correctly, and will function.
Choosing the Right A2 Rear Sight Installation Tool
Types of Tools Available
The market offers a variety of tools designed specifically for installing A2 rear sights. Selecting the right one can make a significant difference in your experience.
There are dedicated tools made specifically for the task. These tools are usually purpose built and designed to function with no other application. These are the most straightforward and often the most reliable choice. Dedicated *A2 Rear Sight Installation Tools* are typically built for one job and thus, are optimized for it.
Some tools are multi-purpose, designed to accommodate various sight types. While versatile, these tools may not always offer the same level of precision and ease of use as dedicated options. They are however, convenient for individuals who own multiple rifles with different sight configurations.
Key Features to Consider
When choosing a tool, consider the following features:
Construction Quality: Opt for tools built from hardened steel or durable aluminum. These materials are designed to withstand the force necessary to install the sight repeatedly. Look for a tool that feels solid and well-made. Cheap tools often have poor machining and may bend or break under pressure.
Ease of Use: The tool should be easy to understand and operate. It should provide clear instructions and a comfortable grip. A tool that is awkward to use is more likely to lead to mistakes.
Compatibility: Ensure the tool is specifically designed for A2 rear sights or that it is compatible with your specific sight model. Double-check the manufacturer’s specifications to confirm that the tool will fit your rifle.
Where to Purchase the Tool
Where to purchase your *A2 Rear Sight Installation Tool* is also a factor. These tools are available at most gun stores. Major online retailers specializing in firearms accessories are also a great option. Local gunsmiths might have tools and offer installation services if you prefer not to do it yourself. Consider reviews and ratings before purchasing to get a feel for the tool’s performance and reliability.
Step-by-Step Installation Guide
Safety Precautions
Before starting, make sure you’re in a safe and well-lit workspace.
Verify the rifle is unloaded. Check the chamber and the magazine. Never assume a firearm is unloaded.
Wear appropriate eye protection. This is critical, as small parts can break or be ejected during the installation process.
Work in a stable environment. A workbench or a solid surface is preferable to prevent accidental drops or injuries.
Preparing the Rifle and Sight
Clean and Inspect: Thoroughly clean the sight and the base on the rifle’s receiver. Remove any debris or grease that could interfere with the installation. Check for any damage to the sight or the receiver.
Alignment: Before installing the sight, make sure that the sight base is properly aligned with the barrel. This is an important step in ensuring proper accuracy.
Using the A2 Rear Sight Installation Tool
Position the tool: Place the sight over the base on your rifle, ensuring that it is properly oriented. Place the tool over the sight assembly. Make sure everything is straight before proceeding.
Apply pressure: If using a dedicated press tool, apply slow, even pressure. This will push the sight into place. If using a hammer-style tool, carefully tap the tool with a mallet or hammer. Avoid striking the tool too hard, as this can damage the sight.
Maintain alignment: Ensure the sight remains aligned with the receiver throughout the installation process. This is crucial for accuracy.
Verification and Adjustment
Check for Proper Seating: Once the sight is fully installed, check for proper seating. The sight should be flush with the receiver.
Make Necessary Adjustments: Use a screwdriver to adjust the windage and elevation settings to center the sight on the target. Fine-tune the settings as needed.
Common Problems and Troubleshooting
Sight Doesn’t Fit
If the sight won’t seat, double-check that you have the correct sight for your rifle. Ensure there is no debris obstructing the mounting point. If the sight is too tight, apply a small amount of gun oil to the base. If the sight is still too difficult to install, take the rifle to a gunsmith.
Sight is Crooked
If the sight is not straight, remove it, re-clean the surfaces, and ensure that you are applying even pressure with the tool. Reinstall the sight, making sure that the sight is perfectly aligned as you drive it in.
Sight is Too Tight or Loose
If the sight is too tight, it may not be easily adjustable or could damage the sight itself. If it’s too loose, it can move during recoil and compromise accuracy. Consider the sight itself. It may be defective and require replacement. If not, it may need to be professionally installed.
Maintenance and Care
Cleaning
Regularly clean your A2 rear sight with a soft cloth and a mild cleaning solution. Avoid abrasive cleaners that can damage the finish.
