Safety First: Preparing for the Task and Gathering Essential Tools
Before embarking on any gun modification, safety should always be the foremost priority. Remember, firearms are inherently dangerous, and mishandling them can lead to serious injury. Before beginning, ensure your firearm is unloaded. This is not just a suggestion; it is the most crucial step.
Start by visually inspecting the magazine well to confirm that no magazine is present. Then, open the bolt and look inside the chamber to verify that it is clear of any ammunition. Finally, physically manipulate the action, pulling back the charging handle and inspecting the chamber one final time. If you can see the interior of the barrel and chamber, it is clear. If, at any point, you are unsure, assume the firearm is loaded and seek professional assistance.
With your firearm safely unloaded, let’s gather the tools and materials you will need. Having everything organized beforehand will streamline the removal process and make the task easier.
You’ll need a sturdy work surface to protect your firearm from scratches. A dedicated gunsmithing mat is an excellent choice, but even a clean, padded surface will suffice. A solid vise with protective jaws or an AR15 bench block are highly recommended. These will securely hold the rifle, allowing you to focus on the task at hand.
The main tools you’ll need are specifically designed for this project. First, you will require the appropriate AR15 front sight adjustment tool. These tools are often small, inexpensive, and purpose-built for adjusting the front sight post. You’ll also need a quality punch set. Within the punch set, you need a roll pin punch, designed to push out the roll pins that secure the front sight base to the barrel, and a pin punch which you can use with your roll pin and it should match the size of roll pin that you have.
Other items to keep on hand include a hammer, protective eyewear, a rag or shop towel, and lubricant. The hammer will be used to gently tap the punches. Eye protection is critical throughout the process. Lubricant, such as penetrating oil or gun oil, can be helpful if the roll pins are stubborn. Lastly, the rag or shop towel helps to wipe up any excess lubricant and keep your work area clean. If you can, a small flashlight can be a great help for peering into tight spaces.
Secure the Firearm
With your tools and safety measures in place, it’s time to begin. Start by securing your AR15. If you are using a vise, clamp the rifle firmly, but not overly tight. The goal is to prevent movement without damaging the firearm. If you are using a bench block, place the rifle in the designated slots, securing it in a stable position.
Removing the Front Sight Post
The front sight post, the vertical piece that aligns with the rear sight, must be lowered before proceeding. This post sits within the front sight base and will be removed. Use the front sight adjustment tool. The procedure is usually a matter of turning the tool to lower the front sight post fully. Be certain that it is fully lowered.
Removing the Securing Roll Pins
The front sight base is connected to the barrel using one or two roll pins. These pins are cylindrical and designed to flex slightly, providing a secure fit. These pins are crucial, so the front sight will function as intended. Locate the roll pin(s) on the front sight base and then insert your appropriate roll pin punch into the roll pin, ensuring the punch is centered. The goal is to drive the roll pin completely through the front sight base. Position the barrel horizontally.
With the punch properly positioned, carefully tap the end of the punch with a hammer. Start with gentle taps and gradually increase the force if necessary. The roll pin should begin to move. Continue tapping until the roll pin is completely removed. If the roll pin seems stuck, stop and reevaluate the situation.
Separating the Base from the Barrel
Once the roll pin(s) are out, the front sight base should come free. Sometimes, it will slide right off. If it doesn’t, gently tap the base. Use a non-marring punch or a small, blunt tool. Place the punch on the side of the base and tap it with your hammer. Remember, gentle and controlled taps are better than excessive force.
Be mindful of the gas tube as you perform this step. The gas tube runs from the gas block, through the front sight base, and into the upper receiver. You will need to remove the gas tube before installing any new sights.
Gas Tube Considerations
The gas tube is an important part of your AR15’s operating system. The gas tube transfers high-pressure gas from the barrel to the bolt carrier group, cycling the action. When removing the front sight, you may need to detach the gas tube. This is usually a simple process, but it is important to handle it with care.
If you are replacing your front sight with a new one, and the new front sight is compatible with the gas tube, carefully install the gas tube back into the new sight base. Ensure that the gas tube aligns properly with the gas block and the upper receiver. Proper alignment is critical for reliable firearm function.
Troubleshooting Common Challenges
Sometimes, things don’t go exactly as planned. Here are some common issues you might encounter and how to address them.
If the roll pin is stuck, don’t panic. First, make sure you are using the correct size roll pin punch. Next, try applying a penetrating oil to the roll pin. Allow the oil to sit for several minutes. Then, try tapping the pin again. If the roll pin remains stuck, consider the possibility of using a larger punch or trying different angles to create better leverage.
Damaged roll pins can be problematic. If you damage a roll pin during removal, you’ll need to replace it. The old pin is unlikely to function well after being damaged. Ensure you use a new roll pin of the correct size and install it carefully.
While less common, stripped threads on set screws (if applicable on your sight) can happen. If this occurs, you may need to use a thread repair kit. Ensure that you select the correct size and pitch for your rifle.
Reassembly and Next Steps
Congratulations! You’ve successfully removed the front sight. Now you’re ready to reinstall a new one or make the modifications you want.
Reassembly is essentially the reverse of the removal process. If you are installing a new front sight base, make sure it is properly aligned on the barrel. With the base in position, carefully insert the roll pin(s), and tap them in until they are flush with the front sight base.
Adjusting the New Front Sight
Once the front sight is reinstalled, you’ll need to adjust it for proper sight alignment. The procedure typically involves using a front sight adjustment tool to raise or lower the front sight post until it is centered. After the front sight is aligned, the rifle should be taken to the range to zero the sights. During zeroing, you’ll fine-tune the sights to ensure that your point of impact matches your point of aim.
Cleaning up Your Work
With the project complete, take a moment to clean up your work area. Wipe down your rifle and tools to remove any excess lubricants or debris. Properly store your tools and any unused parts.
Safety is Paramount
Always handle firearms safely. Never point a firearm at anything you are not willing to destroy. Always keep your finger off the trigger until you are ready to shoot. Wear eye protection whenever you handle firearms or perform modifications.
The AR15 front sight removal is a manageable task. It provides a valuable skill.
Conclusion
Removing your AR15 front sight can be a rewarding experience. It unlocks possibilities for customization and upgrades. By following these steps and taking your time, you can confidently remove your front sight and prepare your rifle for future modifications. Remember the importance of safety and take your time. As you gain experience, you will find yourself comfortable with the AR15 platform.
Whether you’re looking to upgrade your rail system, install an optic, or replace your front sight, the modifications are achievable. Explore, experiment, and enjoy the process of customizing your AR15.
