The AR-15 platform's versatility is legendary, and a key component contributing to that is the upper receiver. Among the many variations, the A2 upper receiver with carry handle remains a popular choice for shooters, offering a classic look and practical features. This guide delves into the specifics of this upper receiver, exploring its benefits, drawbacks, and considerations for potential buyers.
Understanding the A2 Upper Receiver
The A2 upper receiver is easily identified by its integrated carry handle, a feature that distinguishes it from later models with Picatinny rails. This carry handle houses the rear sight, providing a robust and reliable sighting system. Its design, originating from the M16A2 rifle, emphasizes durability and functionality over the modularity found in modern AR-15s.
Key Features and Specifications:
- Integrated Carry Handle: This is the defining characteristic. The handle provides a stable platform for carrying the rifle and incorporates a rear sight, eliminating the need for a separate rear sight mount.
- Fixed Front Sight Post: Usually a post sight, sometimes a gas block with integrated sight. This provides a simple and reliable front sight picture.
- Forged Construction: Typically constructed from durable, forged aluminum alloy, offering robustness and resistance to wear and tear. This makes it highly resilient to the rigors of regular use.
- Limited Rail Space: Unlike modern receivers featuring Picatinny rails along the entire top, the A2 has limited rail space, mostly confined to the carry handle. This restricts the mounting options for optics.
Advantages of Choosing an A2 Upper Receiver
- Classic Aesthetics: For many shooters, the A2's classic look is a major selling point. Its design evokes a sense of nostalgia and heritage associated with the M16A2.
- Robust Construction: The forged construction ensures exceptional durability and reliability, making it suitable for various shooting conditions.
- Reliable Sighting System: The integrated carry handle and front sight post offer a simple, yet effective sighting system that's proven itself over decades of use. This system minimizes potential points of failure associated with multiple components.
- Cost-Effective: A2 uppers are often more affordable than their Picatinny-railed counterparts, making them an attractive option for budget-conscious shooters.
Disadvantages of an A2 Upper Receiver
- Limited Optic Mounting Options: The lack of extensive Picatinny rail space significantly limits the options for mounting modern optics like red dot sights or scopes. Adapting the A2 for modern optics requires additional components and potentially compromises the rifle’s balance.
- Weight: The integrated carry handle adds weight to the overall weapon system, which can be a factor for some shooters, especially during extended use.
- Height: The carry handle increases the height of the sighting plane, which can affect cheek weld and overall shooting comfort, especially for shooters with shorter necks.
Considerations Before Purchasing
Before acquiring an A2 upper receiver, it's crucial to consider your shooting needs and preferences. If you prioritize modern optics and modularity, an A2 upper might not be the ideal choice. However, if you value reliability, durability, and classic aesthetics on a budget, it remains a solid contender. Consider your budget, intended use (e.g., target shooting, home defense, hunting), and personal preferences when making your decision.
Conclusion
The A2 upper receiver with carry handle represents a piece of firearms history, offering a blend of classic design and robust performance. While its limited rail space and increased height present certain limitations compared to modern uppers, its reliability, durability, and cost-effectiveness make it a compelling option for many shooters. Ultimately, the best choice depends on your individual needs and priorities. Understanding the advantages and disadvantages outlined here should help you make an informed decision.
