Understanding A2 Upper Receivers

A1 vs A2 Upper Receivers

The A2 upper receiver is a refined version of the earlier A1 design. Both feature a fixed carry handle and a forward assist, but the A2 brings several notable improvements.

Key Differences:

• Rear Sight Adjustments: The A2’s rear sight is a significant upgrade. It includes a positive-click dial that allows for precise adjustments in both windage and elevation, typically up to 600 yards. This is a step up from the A1’s simpler windage drum.

• Material and Build: Both versions are typically built from high-strength 7075-T6 aluminum, ensuring durability and rigidity. However, the A2’s design improvements make it more user-friendly and reliable.

• Shell Deflector: The A2 includes a shell deflector, which helps direct spent casings away from the shooter, improving safety and comfort.

In summary, the A2 upper receiver offers better sighting options and improved usability over the A1, making it a popular choice for both seasoned shooters and new enthusiasts.

A2 vs A3 Upper Receivers

The A3 upper receiver introduces a different approach compared to the A2, mainly through its flattop design.

Key Differences:

• Flattop Design: Unlike the A2’s fixed carry handle, the A3 features a Picatinny rail on top. This allows for a wide variety of optics and sight attachments, offering greater flexibility for customization.

• Optics and Sights Variety: The A3’s design makes it easier to mount modern optics, red dot sights, and scopes. This can be a significant advantage for those looking to improve their shooting accuracy and versatility.

• User Preference: Choosing between an A2 and an A3 upper receiver often comes down to personal preference. If you value the classic look and integrated rear sight of the A2, it’s the way to go. However, if you prefer the flexibility to add various modern optics, the A3 might be more suitable.

A2 Upper Receiver Benefits:

• Classic military style with a fixed carry handle
• Integrated rear sight with precise windage and elevation adjustments
• Durable construction with 7075-T6 aluminum
• Shell deflector for improved safety

A3 Upper Receiver Benefits:

• Flattop design for mounting various optics
• Greater customization options
• Ideal for modern shooting applications

Understanding these differences helps you choose the right upper receiver for your AR-15 build, whether you prioritize classic aesthetics or modern functionality.

Key Features of A2 Upper Receivers

Material and Construction

The A2 upper receiver with carry handle is built for durability and performance. It uses 7075-T6 aluminum, a high-strength material known for its rigidity and long-lasting durability. This ensures that your upper receiver can handle heavy use without compromising performance.

Anodized Finish

The anodized finish on the A2 upper receiver offers more than just a sleek, black look. It provides excellent corrosion resistance, protecting the receiver from environmental wear and tear. The anodized surface also improves the overall aesthetic appeal, giving your rifle a professional and polished appearance.

M4 Feed Ramps

M4 feed ramps are integrated into the A2 upper receiver to ensure smooth feeding of ammunition. This feature is crucial for reliability and helps prevent jams, making your shooting experience more efficient and enjoyable. The precision machining of these feed ramps ensures a perfect fit with any standard AR-15 lower receiver, contributing to seamless performance.

By focusing on these key features—7075-T6 aluminum for strength, an anodized finish for protection and aesthetics, and M4 feed ramps for reliability—the A2 upper receiver stands out as a robust and dependable choice for any AR-15 build.

Customizing Your A2 Upper Receiver

Choosing the Right Barrel

Customizing your A2 upper receiver with carry handle starts with selecting the right barrel. The barrel is crucial for accuracy, range, and the type of rounds you can shoot.

Barrel Types:
– 4140 Chromoly: Known for its balance of strength and cost.
– 4150 CMV: Popular for its durability and reliability.
– 416R Stainless Steel: Offers excellent accuracy and corrosion resistance.

Length Options:
– 16-inch Barrel: Optimal for a standard build. It provides a good balance between velocity and maneuverability. For instance, a 16-inch barrel can achieve around 2,940 FPS with Federal 62-grain 5.56 ammo.
– Other lengths like 14.5 inches or 20 inches are also available, depending on your specific needs.

Material Considerations:
– Chromoly Steel: Good for general use.
– Stainless Steel: Ideal for precision shooting and environments where corrosion is a concern.

Selecting the Bolt Carrier Group

The Bolt Carrier Group (BCG) is the heart of your AR-15. It affects the reliability and performance of your firearm.

Bolt Carrier Types:
– Full-Auto BCG: Heavier and provides more reliability.
– Semi-Auto BCG: Lighter and may cycle faster.

Material:
– Carpenter 158 Steel: Traditional and highly durable.
– 9310 Steel: Offers similar durability with a smoother finish.

Performance Factors:
– Finish: A chrome-lined or nitride finish can increase the longevity and reliability of your BCG.
– Gas Key Staking: Ensures the gas key remains securely attached, which is crucial for reliable operation.

Optics and Sights

When it comes to optics and sights, the A2 upper receiver offers flexibility despite its fixed carry handle.

Rear Iron Sight Assembly:
– The A2 design includes a sophisticated rear sight adjustable for both elevation (up to 600 yards) and windage. It features a reliable positive-click dial for better performance.

Modern Optics:
– While the A2 carry handle limits some modern optics options, many shooters use carry handle mounts to attach red dots or scopes. This allows for the best of both worlds: classic iron sights and modern optics.

Sight Compatibility:
– Ensure any optic you choose is compatible with the carry handle mount. Many manufacturers offer mounts specifically designed for A2 carry handles.

By carefully selecting your components—barrel, BCG, and optics—you can tailor your A2 upper receiver to meet your specific needs and preferences. This allows for a highly personalized and effective AR-15 build.

Installation and Assembly

Preparing the Upper Receiver

Cleaning and Inspection:
Start by thoroughly cleaning your A2 upper receiver with carry handle. Use a cleaning solvent and a brush to remove any debris or oil. Inspect the receiver for any defects or damage, ensuring it’s in perfect condition before you begin assembly.

Initial Setup:
Gather all the necessary tools and components. You’ll need:
– Armorer’s wrench
– Torque wrench
– Punch set
– Screwdrivers
– Cleaning kit

Installing the Barrel

Barrel Nut and Torque Specifications:
Slide the barrel into the upper receiver, ensuring it seats correctly. Next, thread the barrel nut onto the upper receiver. Use your armorer’s wrench to tighten the barrel nut to 30-80 ft-lbs of torque. It’s crucial to follow the torque specifications to avoid damaging the threads or compromising the integrity of the assembly.

Alignment:
Ensure the gas tube aligns perfectly with the gas block and the upper receiver. Misalignment can cause malfunctioning or damage. Double-check everything before proceeding.

Attaching the Bolt Carrier Group

Bolt Carrier Insertion:
Insert the bolt carrier group (BCG) into the upper receiver. Ensure the bolt is fully forward in the carrier before inserting it. Slide it in smoothly until it seats properly.

Charging Handle:
Insert the charging handle into its slot on the upper receiver, above the BCG. It should slide in easily and lock into place.

Forward Assist:
Check the forward assist to ensure it engages correctly with the bolt carrier. Press the forward assist to verify it pushes the bolt carrier forward without any issues.

Final Assembly and Testing

Function Check:
After assembling, perform a function check. Ensure the charging handle works smoothly and the BCG cycles correctly. Check the safety selector, trigger function, and magazine release.

Test Firing:
Before heading to the range, double-check all components and ensure everything is secure. At the range, start with a single round in the magazine to test basic functionality. Observe the ejection pattern and check for any malfunctions.

Troubleshooting:
If you encounter issues during the function check or test firing, go through the following steps:
– Recheck Alignment: Ensure the gas tube and gas block are aligned correctly.
– Check Torque: Verify the barrel nut torque.
– Inspect BCG: Look for any signs of wear or improper installation.

By following these steps, you can successfully install and assemble your A2 upper receiver with carry handle, ensuring a reliable and functional AR-15 build.
