The AR-9 platform is gaining popularity among shooters and enthusiasts, offering a compelling blend of the familiar AR-15 ergonomics with the power and versatility of the 9mm cartridge. A key element contributing to the AR-9's appeal is the availability of side-charging uppers, which offer distinct advantages over traditional top-charging designs. This guide delves into the specifics of AR-9 side charging uppers, exploring their benefits, drawbacks, and what to consider when choosing one.
Understanding the Appeal of Side Charging
Before we dive into the specifics of AR-9 side charging uppers, let's understand why side charging is becoming a preferred option for many shooters. The primary benefit lies in enhanced operational efficiency, especially in scenarios involving:
-
Suppressed operation: Side charging minimizes gas blowback into the operator's face when using a suppressor, a significant improvement over traditional top charging. The reduced gas pressure contributes to a more comfortable shooting experience, especially during extended shooting sessions.
-
Ambidextrous operation: Side charging uppers cater to both right-handed and left-handed shooters equally, allowing for convenient operation regardless of the user's dominant hand. This feature increases accessibility and adaptability.
-
Faster target acquisition: Some shooters find that the side charging handle allows for quicker manipulation and a faster return to target acquisition after charging the weapon. This can be a significant advantage in dynamic shooting situations.
-
Reduced ejection port cover issues: Eliminates potential issues associated with ejection port covers, especially when shooting suppressed or in adverse conditions, which might hinder the proper functioning of a top-charging system.
Key Features of AR-9 Side Charging Uppers
AR-9 side charging uppers come in various configurations, but several key features are consistently found across different models:
-
Side Charging Handle: The defining feature, located on the left or right side of the upper receiver. The design and placement vary depending on the manufacturer.
-
Bolt Carrier Group (BCG): Specifically designed to accommodate the side charging handle and 9mm cartridge. The BCG is a crucial component determining the reliability and function of the upper receiver.
-
Ejection Port: While the ejection port is still present, its primary function might be slightly altered compared to a traditional AR-15 design as the spent casings are ejected differently due to the side-charging mechanism.
-
Compatibility: Ensure compatibility with your lower receiver and other components. Check the manufacturer's specifications for compatible parts before purchasing.
Potential Drawbacks of Side Charging Uppers
While side charging offers many benefits, it’s crucial to acknowledge potential drawbacks:
-
Increased complexity: Side charging systems can be more intricate mechanically than traditional top-charging systems, potentially leading to increased maintenance needs or the risk of malfunctions if not properly maintained.
-
Reduced Ambidextrous Options (in some cases): While designed to be ambidextrous, some designs might make charging from the non-dominant side slightly less intuitive.
-
Cost: Side-charging uppers often come at a higher price point than their top-charging counterparts, primarily due to their increased complexity in manufacturing.
-
Ergonomics: The placement of the charging handle might not be as ergonomically ideal for every shooter as a traditional charging handle.
Choosing the Right AR-9 Side Charging Upper
Selecting the appropriate AR-9 side-charging upper requires careful consideration of several factors:
-
Brand reputation: Choose a reputable manufacturer known for producing high-quality, reliable AR parts.
-
Materials: Pay close attention to the materials used in construction, prioritizing durable and reliable components.
-
Compatibility: Ensure compatibility with your lower receiver and other components before purchasing.
-
Price: Balance cost with quality and features.
Conclusion
The AR-9 side-charging upper presents a compelling option for shooters looking for enhanced operational efficiency and versatility, especially when operating suppressed or prioritizing ambidextrous operation. However, it’s essential to weigh the benefits against potential drawbacks and carefully consider individual needs and preferences before making a purchase. Thorough research, focusing on manufacturer reputation and component quality, will ensure a satisfactory and reliable addition to your AR-9 build.
