Introduction
In the realm of firearm maintenance and modification, understanding the intricacies of your AR-15 platform is paramount. One seemingly small component that plays a crucial role in protecting your rifle’s delicate internal workings is the dust cover. Whether you’re a seasoned enthusiast or a newcomer to the world of AR-15s, knowing how to remove the AR15 dust cover is an essential skill. This comprehensive guide will walk you through the entire process, providing clear instructions and crucial safety advice to ensure a successful and safe experience.
The AR-15, a modular and versatile rifle, is renowned for its reliability and adaptability. However, like any mechanical device, it requires diligent care and maintenance. The dust cover, also known as the ejection port cover, is a critical element of this maintenance. It acts as a barrier against environmental contaminants that could compromise the function of your rifle. Dirt, debris, dust, and even moisture can find their way into the receiver, potentially leading to malfunctions or damage. Removing the AR15 dust cover is a necessary process for various maintenance tasks, upgrades, or even replacements.
The ability to remove and replace the dust cover opens up a range of possibilities. Whether you are a stickler for pristine cleaning practices, or someone who enjoys customizing their rifle, mastering this procedure will be invaluable. Perhaps you’re upgrading your rifle with a new dust cover, maybe one with a different finish, design, or functionality. Or you might be dealing with a malfunctioning cover that needs repair. The reasons are varied, but the underlying need remains: you need to know how to remove your AR15 dust cover.
Safety First
Before embarking on this task, it is absolutely essential to prioritize safety. Firearms demand respect, and all procedures should be approached with a meticulous focus on safe handling practices. Negligence can have serious consequences. Prior to starting any work, it is crucial to verify that your AR-15 is completely unloaded. Remove the magazine, inspect the chamber to confirm the absence of a round, and always point the muzzle in a safe direction. Ideally, this direction should be toward an area where a discharge, however unlikely, would not cause harm or damage. Never assume a firearm is unloaded; always verify it yourself. The safety of yourself and others is the ultimate priority.
Tools and Materials
The AR-15’s design, characterized by its modularity, means that access to specific components often requires understanding how the rifle is put together. While removing the dust cover is a relatively straightforward procedure, it might require some forethought. This section details what you will need to accomplish this task safely and effectively.
To begin, you will need a few essential tools and materials. These are readily available at most gun stores or online retailers specializing in firearms accessories. The most important item is a punch tool, specifically designed for firearms work. A roll pin punch is the ideal choice, as it is engineered with a concave tip that centers on the pin, preventing slippage and damage to the surrounding receiver. Alternatively, you can utilize a small diameter punch. These punches come in a variety of sizes, so ensure the one you select is appropriately sized to the pin holding your AR15 dust cover in place.
A hammer is also required. A gunsmithing hammer, which often has a smaller head for precision work, is ideal. However, any hammer of suitable size and weight will function, as long as you can control the force applied.
Optional, but sometimes useful, is an armorer’s wrench or specialized tools designed for disassembling the upper receiver of your AR-15. Depending on your specific AR-15 build, you might need to remove certain handguard or other components that may impede access to the dust cover pin. If this is the case, these specialized tools will prove invaluable.
Above all else, appropriate eye protection is non-negotiable. Safety glasses or goggles are essential to protect your eyes from any flying debris during the removal process.
Occasionally, you may want to have additional materials on hand. A replacement dust cover is advisable if you’re installing a new one. A quality firearm lubricant is also beneficial. A few drops applied to the dust cover pin and the dust cover itself can assist in smoother operation and help prevent corrosion.
Step-by-Step Guide
Once you’ve gathered the necessary tools and materials, you can move forward to the central task: removing your AR15 dust cover. Proceed with each step carefully.
Verifying Safety
Before anything else, safety needs to be checked yet again. As mentioned previously, your AR-15 must be unloaded and confirmed as such. Double-check your work. This step cannot be overemphasized. Remember, the rifle should be handled as if it is loaded, at all times.
Removing the Forward Assist (If Necessary)
Before you can even start the dust cover removal, you may need to tackle another component. In some cases, the forward assist, a small button on the side of the upper receiver, may need to be removed to provide adequate clearance for the dust cover to be removed or installed. This is not universally true, however, and depends on your specific AR-15 configuration and the dust cover itself. If you find it’s preventing the dust cover from being completely disengaged, you will need to address it. The process is usually as follows:
The forward assist is generally held in place by a roll pin. Locate this pin, which is typically visible on the side of the upper receiver. Using your punch tool and hammer, carefully tap this pin out. Once the pin is removed, the forward assist can be pulled straight out of the receiver. Keep the small parts organized and in a safe place, such as a small parts tray or a magnetic parts holder.
Locating the Dust Cover Pin
Now, turn your attention to the main component: the AR15 dust cover. Observe it closely. You will notice it pivots on a small pin that runs through the upper receiver. The pin is, as with the forward assist, a roll pin. This is the key to releasing the dust cover.
The direction in which you will need to punch the pin out is usually from left to right, when looking at the rifle from the ejection port side. While some AR-15s might vary slightly in this regard, this is the standard approach. Make a visual note of which side of the receiver the pin appears to sit more flush. This is where you will begin tapping.
Punching Out the Dust Cover Pin
Position your upper receiver on a stable surface. A workbench, protected with a soft mat or a piece of wood, is ideal. This prevents scratching and accidental damage to your receiver.
Take your punch tool and carefully place it on the dust cover pin. Be certain that the punch is centered on the pin and that you have a good purchase. The goal is to apply focused force to the pin, without damaging the surrounding receiver.
With your hammer, begin to tap the punch. Use gentle, controlled taps at first. As the pin starts to move, you can increase the force slightly. Be patient, and avoid striking the punch with excessive force. It’s better to take your time and avoid damaging the receiver. Continue tapping until the pin is completely removed.
As you are driving the pin out, monitor its progress. Ensure the pin is coming out cleanly and that it is not bending or becoming deformed in any way. Make sure it does not damage the receiver.
Removing the Dust Cover
Once the pin is removed, the dust cover should now be free to move. The hinge point of the dust cover should be no longer affixed. Open the dust cover by pulling it out from the receiver. You can then gently pull it away from the ejection port and separate it completely. The dust cover is now detached.
Troubleshooting
Now that you’ve successfully removed your AR15 dust cover, a potential problem or two might be encountered during this process. Let’s address some troubleshooting techniques.
Pin is Stuck
Sometimes, the dust cover pin may be stubborn and refuse to budge. This can be frustrating, but there are several potential solutions. First, ensure that you are using the correct size punch tool. If the tool is too large or too small, it may not effectively drive the pin. Another issue could be debris or corrosion inside the pin hole. In this case, you could apply a penetrating oil to the pin, and allow it to sit for some time before retrying. If the pin remains stuck, you may need to seek assistance from a qualified gunsmith who possesses the expertise and specialized tools to tackle the issue.
Dust Cover Won’t Come Out
Sometimes, the dust cover won’t come out even after the pin is removed. If this occurs, double-check that the forward assist is out of the way if you took that component off. Furthermore, ensure that nothing else is impeding the removal. It could be a slightly misaligned dust cover, or other minor obstruction. In either case, a little bit of investigation should quickly identify the cause.
Installing a New Dust Cover (Optional)
If you are installing a new dust cover, you can follow the steps in reverse, using the same punch, hammer, and possibly a few drops of lubricating oil. Align the new dust cover in the receiver. Insert the dust cover pin and make sure it runs all the way through and is centered on the dust cover’s hinge. Drive the pin into the receiver in the opposite direction. After installing the dust cover, check to make sure it opens and closes smoothly.
Maintenance and Care
Regular maintenance is essential to keep your AR-15 operating reliably. After removing and replacing the dust cover, take the opportunity to thoroughly clean the dust cover and the ejection port area of the upper receiver. Remove any accumulated debris or carbon buildup. Use a gun cleaning solvent and appropriate brushes or tools for this task. Lubrication is also important. Apply a few drops of high-quality gun oil to the dust cover pin and the hinge points. Always use the correct type of lubricants specifically intended for firearms.
Inspect the dust cover for any signs of wear and tear, such as cracks, dents, or excessive play in the hinge. Also inspect the receiver for any damage that might have occurred during pin removal. Addressing these issues early can prevent more serious problems down the line.
Conclusion
Removing and reattaching the AR15 dust cover is a relatively straightforward process, but one that is crucial for the care of your firearm. This step-by-step guide provides the detailed steps to accomplish it with safety in mind. Remember that proper cleaning, lubrication, and maintenance are vital to preserving the reliability and longevity of your AR-15.
While this guide offers comprehensive instructions, if you are unsure about any step, don’t hesitate to seek professional assistance from a qualified gunsmith.
