So, whether you’re new to the AR15 world or looking to enhance your existing setup, prepare to unlock a new level of ergonomic efficiency and customization with a side charging upper.
What is an AR15 Side Charging Upper?
To fully appreciate the AR15 side charging upper, it’s crucial to understand its core components and how they work. The upper receiver, the top half of your rifle’s foundation, is the heart of the action. It houses the bolt carrier group (BCG), barrel, and often, the handguard. The upper receiver is responsible for containing the intense forces generated during firing, as well as guiding the bullet down the barrel.
The standard AR15’s charging handle is traditionally located at the rear of the upper receiver, above the stock. The shooter manipulates this handle, typically by pulling it back and releasing it, to chamber a round from the magazine or manually cycle the action. This rear-mounted charging handle has worked for decades but its position can present some challenges depending on the user’s preferences and equipment.
Enter the AR15 side charging upper. This innovative design relocates the charging handle to the side of the upper receiver, typically on the left side. This change in location fundamentally alters the user experience, offering new ergonomic advantages and opening up possibilities for customization. A side charging upper replaces the standard upper receiver, the new upper receiver also houses all the internal components of a standard upper receiver.
Benefits of Using a Side Charging Upper
The advantages of an AR15 side charging upper go beyond mere aesthetics. This upgrade can provide tangible benefits that enhance the shooting experience, improving speed, ergonomics, and overall performance.
One of the most significant advantages is enhanced ergonomics and speed. The side-mounted charging handle allows for easier manipulation, particularly when the rifle is equipped with optics like scopes or red dots. The rear-mounted handle can sometimes be obscured by the optic or require the shooter to adjust their grip awkwardly to reach it. The side charging handle, however, is often within easier reach, allowing for faster and more efficient charging and clearing of malfunctions. This is especially true for shooters who prefer to keep their firing grip on the weapon while manipulating the charging handle.
Another benefit is increased efficiency in tactical situations. A side charging handle provides a shorter charging stroke compared to the standard AR15’s pull. This is useful when clearing malfunctions in stressful environments where every second counts.
Left-Handed Shooter Advantages
For left-handed shooters, a side charging upper can be a game-changer. The traditional rear-mounted charging handle often requires left-handed shooters to contort their bodies to operate it, making it difficult and less ergonomic. A side charging upper eliminates this issue. This allows left-handed shooters to charge the rifle more naturally, quickly, and comfortably.
Clearance Advantages
Side charging uppers offer improved clearance for various accessories. The position of the side charging handle provides superior access, particularly with optics, suppressors, or other attachments that might obstruct a standard rear-mounted handle. This ensures that the shooter can easily charge or clear the rifle, even with an extensive array of accessories mounted on the weapon.
Side charging also presents an enhanced aesthetic appeal. Many shooters appreciate the sleek and modern appearance of a side charging upper. This offers a visual element and allows for additional customization options.
Considerations and Drawbacks
While an AR15 side charging upper provides several advantages, it’s essential to consider the potential drawbacks. It’s crucial to carefully evaluate these factors before making a purchase.
Compatibility Challenges
One of the most important considerations is compatibility. A side charging upper typically requires a compatible bolt carrier group (BCG) specifically designed to work with the side charging mechanism. Ensure that the BCG you purchase is designed to work with the specific type of side charging upper you choose. Also, certain handguards may not be compatible with a side charging upper, especially those with a fully enclosed design. Make sure that the upper is compatible with your desired handguard setup.
Financial Investment
Unfortunately, side charging uppers generally cost more than standard uppers. This increased cost reflects the more complex design and manufacturing processes. Consider your budget and prioritize features when choosing a side charging upper.
Strength and Durability
The design of a side charging system can affect its durability. Some systems may have more moving parts or utilize weaker materials. Research the manufacturer and read reviews. Prioritize quality materials (e.g., billet aluminum) and robust construction when selecting a side charging upper to ensure longevity and reliability.
Potential Issues and Specific Considerations
One potential issue is the positioning of the ejection port. Some side charging uppers have the ejection port located on the left side to accommodate the charging handle. This arrangement may affect the user’s ejection.
Types of Side Charging Mechanisms
There are several designs for side charging uppers. Understanding these systems will guide you in finding the ideal upper for your needs.
Non-Reciprocating Systems
In a non-reciprocating system, the charging handle remains stationary during firing. The handle doesn’t move during cycling. This design can be preferred because of its simplicity and potential for increased durability.
Reciprocating Systems
In a reciprocating system, the charging handle moves back and forth with the bolt carrier group during firing. Many shooters favor this design because it can be easier to feel the bolt cycling, providing a tactile confirmation of the weapon’s operation.
Other Designs
There are also other unique and innovative side charging designs offered by various manufacturers. These variations might include ambidextrous charging handles, different handle styles, or integrated rail systems.
Choosing a Side Charging Upper
When selecting an AR15 side charging upper, several factors require consideration.
Brand Reputation
Research the brand, as well as the quality and reliability of the manufacturer. Read reviews from experienced shooters to assess their experiences. Reputable brands typically offer better build quality, customer service, and warranties. Some manufacturers are known for producing high-quality side charging uppers.
Material and Construction
High-quality materials are paramount to the longevity and reliability of an upper receiver. Billet aluminum is a popular choice, due to its strength and precision manufacturing. Also, examine the fit and finish of the upper to ensure the quality of the manufacturing process.
Features
Consider the features that are important for your needs. Ambidextrous charging handles are valuable for both right- and left-handed shooters. Rail systems for mounting accessories can also be important.
Compatibility Check
Always double-check that the side charging upper is compatible with your existing AR15 components, including the lower receiver, handguards, and accessories. Compatibility is essential for ensuring proper function and avoiding any potential problems.
Installation and Maintenance
Installing a side charging upper is typically a straightforward process.
Installation Steps
Installation typically involves removing the standard upper receiver from your lower receiver, installing the new side charging upper, and then installing the bolt carrier group (BCG). If you are not experienced with the installation process, it’s always best to consult a professional gunsmith for assistance.
Maintenance
Maintaining a side charging upper requires regular cleaning and lubrication. Follow the manufacturer’s instructions for cleaning and lubrication. Regularly inspect the charging handle for wear and tear, and replace it if necessary.
