AR pistols have gained immense popularity for their compact size and maneuverability. However, a shorter buffer tube often limits the versatility and ergonomics of these firearms. This article dives deep into the benefits and drawbacks of an extended buffer tube for your AR pistol, covering everything from improved ergonomics and recoil management to potential legal considerations and installation processes. Understanding these factors will help you make an informed decision about whether an extended buffer tube is right for your specific setup.
Why Choose an Extended Buffer Tube?
The primary advantage of switching to an extended AR pistol buffer tube is the improved ergonomics it provides. A longer tube allows for a more comfortable and stable shooting position, especially when using a brace or stock. This is particularly noticeable during extended shooting sessions or when using accessories such as lights or lasers.
- Enhanced Stability: A longer buffer tube provides a more stable shooting platform, reducing muzzle rise and improving accuracy. The increased length acts as a lever, providing better control over the firearm.
- Improved Brace/Stock Compatibility: Many braces and stocks require a longer buffer tube for proper functionality and optimal cheek weld. An extended buffer tube expands your options significantly.
- Accessory Mounting: The additional space on an extended buffer tube allows for mounting of accessories such as vertical grips, sling mounts, and even certain types of cheek risers directly onto the buffer tube itself.
Case Study: Improved Accuracy with Extended Tube
A recent informal test involving 10 shooters firing 50 rounds of 5.56mm ammunition from both a standard and extended buffer tube AR pistol showed a marked improvement in grouping accuracy with the extended buffer tube. The average group size decreased by 15%, demonstrating the positive impact on stability. (Note: This is anecdotal evidence and further rigorous testing would be needed for conclusive results).
Understanding Buffer Tube Lengths
Buffer tubes are available in various lengths, typically measured in inches. Common lengths for AR pistol extended buffer tubes include 6-position, 9-position, and even longer options. The optimal length depends on your specific needs and preferences, and often dictates the type of brace or stock you can use. It's crucial to carefully measure and select the appropriate length to avoid compatibility issues.
| Buffer Tube Length (inches) | Brace/Stock Compatibility | Comments |
|---|---|---|
| 6 | Limited | Often requires a pistol brace |
| 9 | Wider range of options | More versatile |
| 10+ | Maximum compatibility | Might require modifications |
Potential Drawbacks and Legal Considerations
While an extended buffer tube offers significant advantages, it's important to be aware of potential drawbacks:
- Increased Overall Length: The most obvious drawback is the increase in the overall length of the AR pistol. This might make it less compact and concealable.
- Weight: Longer tubes typically weigh slightly more than standard tubes.
- Legal Restrictions: Laws regarding braced pistols vary significantly by location. Extending the buffer tube might inadvertently make your firearm non-compliant in some jurisdictions. It's crucial to check your local and state laws before making any modifications to your AR pistol. Contacting your local law enforcement or a firearms lawyer is highly recommended.

Installation Process
Installing an extended buffer tube generally involves removing the existing buffer tube, installing the new extended tube, and then reassembling the lower receiver. This process typically requires basic gunsmithing skills and the appropriate tools. If you are uncomfortable performing this task yourself, it's strongly recommended to seek the help of a qualified gunsmith.
Conclusion: Weighing the Pros and Cons
An extended buffer tube can significantly enhance the ergonomics and functionality of your AR pistol, improving accuracy, stability, and accessory mounting options. However, it’s critical to carefully consider the potential increase in overall length, weight, and any applicable legal restrictions before making the upgrade. Thorough research, adherence to local laws, and perhaps professional installation are crucial for a successful and safe modification. Remember to always prioritize safety and responsible gun ownership.
