Building your own AR-15 can be a rewarding experience, offering customization and a deep understanding of your firearm. A crucial component of this process is selecting the upper receiver. Aero Precision is a popular choice among builders for its reputation for quality and affordability. This guide delves into what constitutes a complete Aero Precision upper, its advantages, and factors to consider when choosing one.
Understanding the Components of a Complete Aero Precision Upper
A "complete" Aero Precision upper receiver group isn't just the upper receiver itself; it's a fully assembled unit ready to be mated with your lower receiver. This typically includes:
- Upper Receiver: The heart of the system, this houses the bolt carrier group and barrel. Aero Precision offers various materials and finishes, influencing both weight and durability.
- Bolt Carrier Group (BCG): This reciprocates within the upper receiver, cycling the ammunition. Aero Precision offers different BCGs, ranging from their standard offerings to enhanced versions with features like nickel boron coating for smoother operation.
- Barrel: The barrel is where the projectile is propelled. Aero Precision uppers come with barrels of various lengths, calibers (.223 Wylde, 5.56 NATO, etc.), and profiles (government, lightweight, etc.), greatly affecting accuracy and recoil.
- Gas System: This directs gas from the barrel to cycle the BCG. Common options include carbine-length and mid-length systems, influencing performance and reliability.
- Handguard: Protecting the barrel and gas system, the handguard provides a place to attach accessories like lights, lasers, and vertical grips. Aero Precision offers various handguards in different materials, lengths, and mounting systems (M-LOK, KeyMod).
- Charging Handle: Used to manually cycle the bolt, Aero Precision often includes a standard charging handle but might offer upgraded options separately.
- Forward Assist: Used to assist in chambering a round if needed (not present on all models).
- Ejection Port Cover: Keeps debris out of the receiver.
Advantages of Choosing a Complete Aero Precision Upper
Opting for a complete Aero Precision upper offers several key advantages:
- Convenience: It eliminates the need to source and assemble individual components, saving time and effort.
- Compatibility: Aero Precision components are designed to work seamlessly together, ensuring proper function and reliability.
- Cost-Effectiveness: Purchasing a complete upper can often be more cost-effective than buying parts individually, particularly for those new to AR-15 building.
- Quality Control: Aero Precision maintains high standards in manufacturing, giving you confidence in the quality and durability of your upper.
Factors to Consider When Selecting an Aero Precision Upper
While the convenience is appealing, careful consideration of several factors is essential:
- Caliber: Choose a caliber compatible with your intended ammunition and application.
- Barrel Length: Shorter barrels offer increased maneuverability, but potentially reduce accuracy and effective range. Longer barrels typically offer increased accuracy and range.
- Gas System Length: The gas system length affects the felt recoil and reliability.
- Handguard Style and Length: Consider your preference and intended accessories. M-LOK and KeyMod systems offer versatile mounting options.
- Budget: Aero Precision offers various price points, allowing you to find an upper that suits your needs and budget.
Beyond the Basics: Aero Precision's Upper Variations
Aero Precision offers a wide range of uppers, extending beyond the standard configurations. They provide options tailored for specific needs, including those designed for different shooting disciplines like precision rifle or close-quarters combat.
Choosing the right complete Aero Precision upper is key to a successful AR-15 build. By carefully considering the components and factors outlined above, you can select an upper that meets your individual needs and expectations, enhancing your shooting experience. Remember to always prioritize safety and consult reputable resources when working with firearms.
