The AR-15 platform's modularity allows for countless configurations, and the choice of sighting systems is a key aspect of customization. For those seeking a retro aesthetic or a robust, reliable backup sighting solution, the combination of a carry handle upper receiver and a corresponding front sight post is a popular choice. This guide delves into the specifics of AR-15 carry handle and front sight combos, exploring their advantages, disadvantages, and considerations for both experienced and novice AR-15 owners.
Understanding the Carry Handle Upper Receiver
The carry handle upper receiver is a distinctive feature of early AR-15 designs. Integrated into the upper receiver itself, the carry handle houses the rear sight, eliminating the need for a separate rear sight assembly. This design offers several benefits, including:
-
Enhanced Durability: The integral design provides a robust and rigid sighting system, less prone to damage or misalignment compared to detachable rear sights.
-
Simplified Installation: Installation is straightforward, requiring only the upper receiver and the front sight post. No additional mounting hardware is necessary.
-
Classic Aesthetic: The carry handle evokes the classic look of the original M16 rifle, appealing to many shooters who appreciate the platform's history.
Choosing the Right Front Sight Post
The front sight post is equally crucial. When paired with a carry handle upper, it ensures proper sight alignment for accurate shooting. Key considerations when selecting a front sight post include:
-
Height: The height of the front sight post must be compatible with the rear sight's elevation to achieve proper zeroing at various ranges. Improper height can lead to significant point-of-impact errors.
-
Material: Front sight posts are typically made from steel or aluminum. Steel is more durable but heavier, while aluminum offers a lighter weight option.
-
Sight Post Design: Some front sight posts feature a wider post for improved visibility in low-light conditions, while others opt for a narrower profile for precise aiming.
Advantages of an AR-15 Carry Handle and Front Sight Combo
This classic setup offers several practical advantages:
-
Reliable Backup Sights: The integrated nature of the carry handle provides a reliable backup sighting solution should your primary optic fail.
-
Cost-Effective Option: Carry handle uppers and front sight posts are often more affordable than separate, detachable sighting systems.
-
Simplified Maintenance: Fewer parts mean less to clean, maintain, and potentially replace.
Disadvantages of an AR-15 Carry Handle and Front Sight Combo
Despite its benefits, this setup also has limitations:
-
Limited Eye Relief: The fixed position of the carry handle sight restricts the shooter's eye relief, making it less adaptable to different shooting styles and positions.
-
Weight: The carry handle adds weight to the upper receiver, which might be undesirable for some users.
-
Obstructed Optic Mounting: The carry handle physically prevents the mounting of most optics directly to the upper receiver. While some users utilize a riser to mount an optic above the handle, this can impact the overall profile and handling.
Compatibility and Installation
Ensuring compatibility between the carry handle upper and the front sight post is essential. Most standard AR-15 front sight posts are compatible with carry handle uppers, but always verify specifications to avoid issues. Installation is usually straightforward, involving attaching the front sight post to the gas block. However, consult your specific manufacturer's instructions for detailed guidance.
Conclusion
The AR-15 carry handle and front sight combo presents a compelling option for shooters seeking a reliable, durable, and cost-effective sighting solution. While it possesses limitations concerning eye relief and optic mounting, its strengths in backup sighting, simplicity, and classic aesthetic make it a worthwhile consideration, especially for those valuing robustness and a retro look. Careful consideration of the advantages and disadvantages, along with verifying compatibility, is crucial before making a purchase.
