The world of AR-15 builds is constantly evolving, with new features and designs emerging to meet the demands of shooters and enthusiasts. One such innovation gaining popularity is the BCA (Bear Creek Arsenal) side charging upper receiver. This design offers a unique solution to some common problems associated with traditional top-charging AR-15s, but it's crucial to understand its advantages and potential drawbacks before committing to a build. This comprehensive guide will explore the intricacies of BCA side charging uppers, helping you determine if this configuration is the right choice for your next AR-15 project.
What is a BCA Side Charging Upper?
A BCA side charging upper receiver is an AR-15 upper receiver that features a charging handle located on the side of the receiver, rather than the traditional top position. This seemingly small change offers several advantages, primarily addressing the challenges encountered with traditional top charging systems, particularly in close-quarters combat (CQB) situations or when using optics with high mounts.
Key Features of BCA Side Charging Uppers:
- Side-mounted charging handle: The defining characteristic, enabling ambidextrous operation and easier manipulation in various shooting positions.
- Improved ergonomics: The side charging handle allows for smoother operation, especially when using magnified optics, scopes, or red dot sights with tall mounts.
- Enhanced CQB capabilities: The side charging handle is less likely to interfere with accessories or obstruct the user's view during close-quarters engagements.
- Reduced bolt carrier interference: In some instances, a traditional charging handle can interfere with the bolt carrier group. The side charging handle can mitigate this issue.
- Ambidextrous operation: Both left and right-handed shooters can easily manipulate the charging handle.
Benefits of Choosing a BCA Side Charging Upper
The advantages of opting for a BCA side charging upper are significant and cater to a broad range of shooting styles and preferences.
Enhanced Usability and Speed:
- Faster target acquisition: The side charging handle prevents interference with optics and allows for quicker target acquisition.
- Improved manipulation: The placement of the handle offers a more natural and intuitive charging action for many shooters.
Improved Reliability in Certain Situations:
- Reduced chance of optic interference: High-mounted optics often clash with traditional charging handles. The side charging system avoids this issue entirely.
- Enhanced maneuverability in CQB: The side charging handle prevents accidental snagging on gear or obstacles, leading to improved maneuverability in cramped environments.
Potential Drawbacks and Considerations
While BCA side charging uppers offer numerous benefits, it's important to consider the potential drawbacks:
Potential for Increased Wear:
- Potential for increased wear: Some users report increased wear on the charging handle and receiver due to the side-mounted design. This is however not universally reported. Thorough lubrication and proper maintenance practices can minimize this concern.
Compatibility Issues:
- Compatibility with certain accessories: While most accessories are compatible, ensure compatibility before purchasing. Always check manufacturer specifications.
Price Point:
- Price point: Side charging uppers might be slightly more expensive than traditional uppers. The price difference varies depending on the manufacturer and features.
Conclusion: Is a BCA Side Charging Upper Right for You?
BCA side charging uppers offer a compelling alternative to traditional top-charging systems. The improved ergonomics, enhanced maneuverability, and reduced optic interference are significant benefits, particularly for CQB shooting or users employing high-mounted optics. However, potential compatibility issues and slightly higher price should be taken into account. Careful consideration of your individual needs and shooting style is crucial in determining if a BCA side charging upper is the right fit for your AR-15 build. Always research and compare options before making your final decision.
