The AR-15 platform's enduring popularity stems from its modularity and adaptability. One key component contributing to this versatility is the upper receiver, and within that category, the A2 carry handle upper holds a special place. This upper receiver, characterized by its integrated carry handle, represents a classic design choice often favored by shooters for its robust build, distinctive look, and specific advantages. This in-depth guide will explore the A2 carry handle upper, examining its features, benefits, drawbacks, and overall suitability for various applications.
Understanding the A2 Carry Handle Upper's Design
The A2 carry handle upper differs significantly from its more modern flattop counterparts. Its most defining feature is the integrated carry handle, which houses the rear sight. This design, while seemingly simple, provides several key advantages. The carry handle itself acts as a robust mounting point for the rear sight, resulting in superior sight stability and durability compared to some more modern, Picatinny rail-mounted systems. This integrated design eliminates the need for separate mounting hardware and reduces the potential points of failure, particularly in adverse conditions.
Key Features of the A2 Carry Handle Upper
- Integrated Carry Handle/Rear Sight: This is the most distinguishing characteristic, offering a solid, built-in sight system.
- Forward Assist: Most A2 uppers include a forward assist, allowing for easier chambering of a round if needed.
- Dust Cover: A dust cover protects the ejection port from debris.
- M4 Feed Ramps: While not always present on all A2 uppers, many incorporate M4 feed ramps for smoother feeding and reduced malfunctions.
- Forged Construction: Typically forged from 7075-T6 aluminum, providing a durable and rigid platform.
Advantages of Choosing an A2 Carry Handle Upper
- Robustness and Reliability: The integrated design reduces points of failure, leading to increased reliability.
- Simplified Zeroing: The fixed rear sight simplifies zeroing compared to adjustable sights.
- Cost-Effectiveness: Often more affordable than flattop uppers, especially when considering the included carry handle and rear sight.
- Classic Aesthetic: Many shooters appreciate the classic military look and feel of the A2 upper.
- Less Rail Space Required: Compared to flattop uppers, it may require less accessory mounting.
A2 Carry Handle Upper vs. Flattop Upper: A Comparison
While the A2 carry handle upper has its merits, it's crucial to compare it to the prevalent flattop upper receiver design to understand its place in the modern AR-15 world.
Feature | A2 Carry Handle Upper | Flattop Upper |
---|---|---|
Rear Sight | Integrated carry handle/rear sight | Picatinny rail for various sights |
Versatility | Limited accessory mounting options | Extensive accessory mounting options |
Weight | Slightly heavier | Generally lighter |
Cost | Generally lower | Generally higher |
Optics Mounting | Requires a scope rail or separate mounting system | Direct mounting of optics on rail |
Considerations When Using an A2 Carry Handle Upper
While the A2 upper provides a reliable platform, there are considerations to keep in mind:
- Limited Rail Space: The lack of a full Picatinny rail restricts accessory mounting. Adding a Picatinny rail to the top of the carry handle may improve versatility but adds weight and cost.
- Sight Height: The higher sight line may not be ideal for all shooters.
- Co-witnessing: Using optics with the integrated sights requires careful consideration of co-witnessing.
Case Study: A2 Uppers in Competition Shooting
While not the most popular choice for modern competitive shooting, the A2 carry handle upper can find a niche in certain disciplines. Its inherent reliability makes it a viable option for shooters valuing ruggedness and simplicity over extreme versatility. Some competitors might prefer the fixed sight for its ease of zeroing and reduced potential for malfunction.
Conclusion: The Enduring Appeal of the A2 Carry Handle Upper
The A2 carry handle upper, while not the cutting-edge design, remains a relevant and valuable component in the AR-15 world. Its simplicity, robustness, and cost-effectiveness make it an attractive option for shooters prioritizing reliability and classic aesthetics. While the flattop upper offers greater versatility, the A2 upper holds its own, particularly for those who value a more streamlined, less cluttered setup. Ultimately, the best choice depends on individual needs and preferences. Understanding the A2 carry handle upper's advantages and limitations will allow shooters to make an informed decision about whether it's the right choice for their build.
