AR pistol builds are increasingly popular, offering a compact and maneuverable platform for personal defense or recreational shooting. However, the short length of a standard buffer tube can present challenges in terms of ergonomics and shooter comfort. This is where an extended buffer tube comes in. This guide will delve into the benefits, considerations, and best practices for choosing and installing an extended buffer tube on your AR pistol.
Why Choose an Extended Buffer Tube?
The primary reason shooters opt for an extended buffer tube is to improve ergonomics. A longer tube allows for a more comfortable and stable shooting position, particularly when using a brace or stock. Here's a breakdown of the key advantages:
-
Enhanced Cheek Weld: A longer tube provides a more natural and consistent cheek weld, crucial for accurate shot placement, especially during rapid firing.
-
Improved Stability: The extended length contributes to better weapon control and reduces muzzle rise, leading to improved accuracy and follow-up shots.
-
Increased Brace/Stock Options: Many braces and stocks require a longer buffer tube for proper function and comfortable operation. An extended tube opens up a wider array of customization options.
-
Reduced Recoil: While not a primary function, the added length can subtly reduce felt recoil by providing a longer lever arm.
Choosing the Right Extended Buffer Tube
Selecting the appropriate extended buffer tube involves several key factors:
Length:
Buffer tubes are measured in inches. Common extended lengths range from 6 inches to 9 inches. The optimal length depends on personal preference, the type of brace or stock used, and the overall dimensions of your AR pistol. Consider your build's intended purpose – a longer tube might be better suited for a braced pistol used for home defense, while a shorter one might be preferable for concealed carry (though this is rarely done with AR pistols).
Material:
Most extended buffer tubes are constructed from aluminum alloy, offering a balance of strength and lightweight design. Ensure the tube is appropriately anodized or coated for corrosion resistance.
Compatibility:
Verify compatibility with your lower receiver and chosen brace or stock before purchasing. Different manufacturers may use slightly varying specifications.
Buffer Tube Weight:
While the weight difference between a standard and extended buffer tube might seem negligible, consider the overall weight of your build, especially if aiming for a lightweight configuration.
Installation Considerations
Installing an extended buffer tube is generally straightforward but requires attention to detail. Improper installation can lead to malfunctions or damage. Always consult your buffer tube manufacturer's instructions. Generally, the process involves:
-
Removing the existing buffer tube: This usually involves removing the castle nut and end plate.
-
Installing the new extended buffer tube: Ensure proper alignment and secure tightening of the castle nut.
-
Reinstalling the buffer and spring: Pay close attention to the correct orientation of the spring and buffer.
-
Attaching your brace or stock: Securely mount your chosen brace or stock to the extended buffer tube, ensuring proper function and stability.
Conclusion: Upgrading Your AR Pistol Ergonomics
An extended buffer tube can significantly enhance the ergonomics and shootability of your AR pistol. By carefully considering length, material, compatibility, and installation, you can greatly improve your shooting experience and make your AR pistol a more effective and enjoyable firearm. Remember to prioritize safety and always follow manufacturer instructions for installation.
