Choosing the right sling mount for your AR-15 is crucial for comfortable carrying, stable shooting, and overall functionality. This guide dives deep into the world of AR-15 rear sling mounts, exploring different types, installation methods, and key considerations to help you make an informed decision.
Understanding AR-15 Sling Mount Options
The rear sling mount is a critical component of your AR-15's sling setup. Unlike front mounts, which offer a wider variety of options, rear mounts generally fall into a few key categories:
1. Buffer Tube Mounts: The Most Common Choice
These are by far the most prevalent type of rear sling mount. They attach directly to the receiver extension (buffer tube) using a variety of methods:
-
Slotted Buffer Tube Mounts: These utilize the slots already present on most buffer tubes. They're generally inexpensive and easy to install, but can sometimes be loose or prone to slippage.
-
End Plate Mounts: These replace the standard buffer tube end plate. They're generally more robust and secure than slotted mounts, offering a more stable platform for your sling. They often incorporate QD (Quick Detach) swivel sockets for rapid sling attachment and detachment.
-
Integrated Buffer Tubes: Some buffer tubes come with built-in sling mounts, eliminating the need for a separate component. This is a streamlined solution, often offering a clean and integrated look.
2. Receiver Extension Mounts (Non-Buffer Tube):
Less common, these mounts attach directly to the receiver extension itself, often requiring specific tools or modifications for installation. They provide a secure mounting point, but may not be compatible with all receiver extensions.
3. Castle Nut Sling Mounts: A Solid, Integrated Solution
These mounts replace the castle nut at the end of your buffer tube. Offering a very secure and integrated solution, they often feature integrated QD sockets. Proper torque is essential during installation.
Factors to Consider When Choosing a Rear Sling Mount
Several factors influence your choice of rear sling mount:
-
Material: Aluminum is the most common material, offering a balance of strength and weight. Steel offers superior durability but adds significant weight. Polymer options exist, offering lightweight solutions but potentially sacrificing durability.
-
Mounting Method: Consider the ease of installation and the security of the mount. End plate mounts generally provide superior stability compared to slotted mounts.
-
QD Swivel Compatibility: Quick detach (QD) swivels are essential for rapid sling attachment and detachment. Ensure your chosen mount is compatible with your preferred QD swivels.
-
Weight: While strength is important, excess weight can negatively impact your overall rifle's balance and handling.
-
Aesthetics: While purely subjective, the overall look and feel of the mount can contribute to your satisfaction with the upgrade.
Installation: A Quick Overview (Always Refer to Manufacturer Instructions)
The installation process varies depending on the chosen mount type. Generally, slotted mounts require simple insertion and tightening, while end plate mounts involve replacing the existing end plate. Castle nut mounts require specialized tools and knowledge to ensure proper torque and prevent damage to the receiver extension. Improper installation can lead to component failure and potential injury, so always consult the manufacturer's instructions.
Conclusion: Finding the Perfect Fit
Selecting the right AR-15 rear sling mount requires considering your individual needs and preferences. Understanding the different types, their advantages and disadvantages, and the importance of proper installation will ensure a secure and reliable sling setup, enhancing your shooting experience and overall comfort. Remember, investing in a high-quality mount is an investment in your rifle's safety and performance.
