Maintaining your upper receiver is essential to ensuring its optimal performance and longevity. Regular cleaning is a key part of this maintenance. Here are the steps to clean it effectively:
|🟣 Disassemble:||Start by ensuring that your firearm is unloaded before proceeding with the disassembly. Take out the bolt carrier group and charging handle, followed by removing the handguard if it’s removable. Be sure to consult the user’s manual for specific instructions to avoid damaging any components.|
|🟣 Cleaning the Chamber and Bore:||Use a bore brush attached to a cleaning rod to scrub the inside of the barrel. Apply a suitable gun-cleaning solvent to the brush before starting. Brush the chamber and bore thoroughly to remove any residue or dirt.|
|🟣 Cleaning the Bolt Carrier Group and Charging Handle:||These components often accumulate dirt and residue due to constant use. Use a small brush and cleaning solvent to clean these parts meticulously. Make sure to pay attention to small crevices and slots.|
|🟣 Cleaning the Upper Receiver:||Use a clean cloth to wipe down the inside of the upper receiver. For stubborn debris, you may use a nylon brush. Apply solvent to areas with carbon build-up and let it sit for a few minutes before scrubbing.|
|🟣 Lubrication:||Once all components are clean and dry, apply a high-quality firearm lubricant. Focus on the bolt carrier group, charging handle, and inside of the upper receiver. This will ensure smooth operation and prevent wear and tear.|
|🟣 Reassemble:||After all the components are cleaned and lubricated, reassemble your firearm. Always check its functionality after reassembly to ensure that it’s operating correctly.|

What Are Upper Receivers Made From? 🎯
Upper receivers are typically made from materials that are selected for their ability to withstand significant wear and tear, as well as their capacity to handle the heat and pressure generated during the firing process.
⬜ One of the most common materials used in the manufacturing of upper receivers is 7075-T6 aluminium. This specific type of aluminium is a high-strength alloy, characterized by its light weight and remarkable durability. It is considered an industry standard for upper receivers because of its excellent resistance to corrosion, its ability to withstand high temperatures, and its fantastic strength-to-weight ratio. The “T6” indicates that this aluminium alloy goes through a process of heat treatment and artificial ageing to increase its hardness and durability.
⬜ Another material often used in the production of upper receivers is 6061 aluminium. While not as strong as 7075-T6, it is easier to machine and weld, and it still provides excellent durability and corrosion resistance. It is often used in the production of more economical upper receivers.
⬜ Recently, there has been a growing interest in using polymers in the construction of upper receivers. Polymer upper receivers are desirable for their lightweight and cost-effectiveness. However, while they hold up well under normal conditions, they may not offer the same level of durability and heat resistance as their aluminium counterparts.
⬜ Some high-end upper receivers are also made from steel or titanium. Steel is highly durable and can handle a large amount of heat and pressure, but it is also heavier than aluminium. Titanium, on the other hand, is lighter than steel but stronger and more heat-resistant, although it can be more expensive.

Installing the requires a bit of technical knowledge, but with the right tools and instructions, it can be accomplished by any firearm enthusiast. Here’s a detailed guide to help you understand the process.
🔘 Before you begin the installation process, ensure that your workspace is clean, well-lit, and free of any potential hazards. It’s also advisable to have the manufacturer’s manual on hand, as it will provide specific instructions related to your specific model.
🔘 Start by separating the upper receiver from the lower receiver of your firearm. This is typically accomplished by pushing out the takedown pins located on the lower receiver. Once the takedown pins are removed, the upper and lower receivers should separate easily.

Once the bolt carrier group is removed, you can pull the charging handle all the way back and it should slide out of the receiver.
🔘 Now you are ready to install it. Insert the charging handle into the upper receiver, making sure to align the grooves on the handle with the tracks inside the receiver. Once the charging handle is in place, you can insert the bolt carrier group. Make sure the bolt is extended from the carrier and the gas key fits into the channel of the charging handle.
🔘 Finally, line up the holes on the upper receiver with the holes on the lower receiver and push the takedown pins back in. This should secure the upper receiver to the lower receiver. Once everything is securely fitted, give your firearm a quick function check to ensure everything is working correctly.
