Building an AR pistol? Selecting the right buffer tube is crucial for functionality, reliability, and legal compliance. This guide delves into the key considerations when choosing a buffer tube for your AR pistol build, ensuring you make an informed decision.
Understanding AR-15 Buffer Tubes and Their Role
The buffer tube isn't just a cosmetic addition; it's a critical component of your AR-15 pistol's operating system. It houses the buffer spring and buffer, which manage the recoil impulse after each shot. The correct buffer tube length directly impacts the cycling of your firearm and overall reliability. Choosing the wrong one can lead to malfunctions and potential damage.
Key Factors to Consider:
-
Length: This is arguably the most important factor. Buffer tubes are available in various lengths, commonly measured in inches. The most common lengths for AR pistols are 6-position and pistol-length. The choice depends on your desired overall length and brace/stock configuration. Remember: Laws regarding overall length vary significantly by location; check your local and state regulations before proceeding.
-
Material: Most buffer tubes are constructed from steel or aluminum. Steel offers superior durability and longevity, while aluminum provides a lighter-weight option. The choice often comes down to personal preference and budget.
-
Manufacturer: Several reputable manufacturers produce AR-15 buffer tubes, each with its own reputation for quality and reliability. Researching different brands and reading reviews can help you choose a tube that meets your needs and expectations.
-
Compatibility: Ensure your chosen buffer tube is compatible with your lower receiver and other components. While most buffer tubes are standardized, slight variations can exist. Always verify compatibility before purchasing.
6-Position vs. Pistol-Length Buffer Tubes: What's the Difference?
The key difference lies in adjustability. A 6-position buffer tube allows for adjustment of the length of pull, accommodating different shooter preferences and potentially allowing the addition of a brace at a later date. A pistol-length buffer tube is fixed in length and generally requires a pistol brace designed for its specific length.
Choosing the Right Length:
- Consider your brace: The brace you intend to use will dictate the optimal buffer tube length. Most braces are designed for specific buffer tube lengths.
- Overall length regulations: Be meticulously aware of the legal limitations on overall weapon length in your area. Using a shorter buffer tube can help keep your AR pistol within legal limits.
- Personal preference: If you anticipate wanting to adjust the length of pull in the future, the 6-position tube offers more flexibility.
Beyond the Basics: Features and Considerations
While length and material are primary factors, other aspects might influence your decision:
- Buffer tube weights: Some manufacturers offer buffer tubes with varying weights. A heavier buffer tube can absorb recoil more effectively, but it will add weight to your firearm.
- Finish: Consider the finish of the buffer tube. A durable finish will protect the tube from corrosion and wear.
Conclusion: Making the Right Choice for Your AR Pistol Build
Selecting the correct buffer tube for your AR pistol build is crucial for reliable operation and legal compliance. By carefully considering the factors outlined above—length, material, compatibility, and any additional features—you can confidently choose the best buffer tube for your specific needs. Always double-check your local regulations and verify compatibility with other components before making a purchase. Remember, a well-informed decision today can prevent issues down the line.
