The AR-15 platform's enduring popularity stems from its modularity and adaptability. For many shooters, especially those interested in a classic aesthetic or a robust, reliable build, the A2 upper receiver with carry handle remains a compelling choice. This guide delves into the features, benefits, and considerations of this specific configuration.
Understanding the A2 Upper Receiver
The A2 upper receiver distinguishes itself through its integrated carry handle, which houses the rear sight. This design, a hallmark of the M16A2 rifle, offers several advantages and disadvantages compared to modern, flat-top receivers.
Advantages of the A2 Carry Handle Upper:
- Built-in Rear Sight: The most obvious benefit is the integrated, robust rear sight. This eliminates the need for a separate rear sight, simplifying setup and reducing cost. The A2 sight is known for its durability and reliability, even under harsh conditions.
- Increased Rigidity: The carry handle contributes to the overall rigidity of the upper receiver, potentially enhancing accuracy, especially with heavier barrels or during sustained firing.
- Classic Aesthetic: Many shooters appreciate the classic, military-inspired look of the A2 upper receiver, which evokes a sense of heritage and reliability.
- Simplicity: Fewer parts mean less potential for malfunction and easier maintenance.
Disadvantages of the A2 Carry Handle Upper:
- Limited Optic Mounting Options: The integrated carry handle limits the options for mounting modern optics like red dot sights or scopes. While some solutions exist (such as rail adapters), they can add cost and complexity.
- Higher Profile: The carry handle raises the overall profile of the rifle, which can impact low-light shooting and close-quarters engagements.
- Weight: The carry handle adds a small amount of extra weight to the rifle.
Choosing an A2 Upper Receiver: Key Considerations
Selecting the right A2 upper receiver requires careful consideration of several factors:
Material:
- Aluminum Forgings: Most A2 uppers are made from high-quality aluminum forgings, offering a good balance of strength and weight. Look for forgings, not cast uppers, for superior durability.
Barrel Length and Profile:
- Various Options: A2 uppers are available with a range of barrel lengths (e.g., 16", 20") and profiles (e.g., government profile, lightweight profile). Consider your intended use – shorter barrels are more maneuverable, while longer barrels offer increased accuracy and velocity.
Finish:
- Anodizing: Anodizing provides corrosion resistance and a durable finish. Look for a hard-anodized finish for maximum protection.
Manufacturer Reputation:
- Research Thoroughly: Choose a reputable manufacturer with a proven track record of producing high-quality AR-15 parts. Read reviews and compare offerings before making a decision.
A2 Upper Receivers: Modern Applications
While the A2 upper receiver might seem outdated in the age of modularity and Picatinny rails, it still holds its own in several scenarios:
- Budget-Friendly Builds: The integrated rear sight reduces the overall cost of building an AR-15.
- Classic AR-15 builds: For shooters seeking a faithful recreation of classic M16A2 rifles, the A2 upper is essential.
- Reliability-focused builds: The simplicity of the A2 design contributes to enhanced reliability.
Conclusion:
The A2 upper receiver with carry handle offers a robust and reliable option for AR-15 builders and shooters. Understanding its advantages and limitations is crucial for making an informed decision. Weigh the benefits of its integrated sight and classic aesthetic against the limitations in optic mounting options to determine if it’s the right choice for your needs. Remember to prioritize quality manufacturing and choose reputable brands to ensure a durable and safe shooting experience.
