When building or customizing an AR-15, enthusiasts know that every component plays a crucial role in performance, reliability, and comfort. Among these components, AR15 buffer tubes (also called receiver extensions) are often overlooked but are essential to the overall function and customization of the firearm. Though buffer tubes may seem like simple metal cylinders, a wide variety of options are available, each with a significant impact on your shooting experience.
1. Mil-Spec Buffer Tube
What is a Mil-Spec Buffer Tube?
The Mil-Spec (Military Specification) buffer tube is the standard for most AR-15 builds, ensuring compatibility with a wide variety of Mil-Spec aftermarket stocks and accessories. Mil-Spec buffer tubes are designed for durability and performance in military-grade rifles, making them a reliable choice for enthusiasts.
Key Features of Mil-Spec Buffer Tubes
- Material Quality: Typically made from 7075-T6 aluminum, known for its superior strength and lightweight characteristics.
- Dimensions: The Mil-Spec buffer tube has a 1.14-inch outer diameter, ensuring compatibility with a wide range of stocks.
- Versatility: These buffer tubes offer broad compatibility, making them a favorite for a variety of aftermarket parts.
- Durability: Often finished with anodized coatings for enhanced corrosion resistance and longevity.
Applications
Mil-Spec buffer tubes are ideal for those building AR-15s with a broad range of compatible options. They are well-suited for tactical, professional, and sports shooting applications, providing strength and versatility.
2. Commercial Buffer Tube
What is a Commercial Buffer Tube?
Commercial buffer tubes are more affordable and are typically used in budget AR-15 builds. They have slightly different dimensions than Mil-Spec tubes, often offering a more budget-friendly solution for general consumers.
Key Features of Commercial Buffer Tubes
- Material Quality: Often made from 6061-T6 aluminum, which is still durable but less robust than the 7075-T6 used in Mil-Spec tubes.
- Dimensions: The Commercial buffer tube generally has a 1.17-inch outer diameter, making it incompatible with Mil-Spec stocks.
- Cost-Effectiveness: More affordable, ideal for budget builds or those who don’t need the additional durability of a Mil-Spec tube.
- Slightly Wider Profile: Offers a thicker wall and added robustness for consumer-grade builds.
Applications
Commercial buffer tubes are commonly used in entry-level AR-15 builds and by casual shooters. They’re great for those on a budget or recreational shooters who don't require military-grade durability.
3. A5 Buffer Tube
What is an A5 Buffer Tube?
The A5 buffer tube is a specialized receiver extension designed for high-performance AR-15 builds. It’s developed by VLTOR and provides a unique combination of Mil-Spec-style design with an extended length, enhancing the recoil management and performance of the rifle.
Features and Benefits of A5 Buffer Tubes
- Extended Length: The A5 tube’s extended length allows for the use of a specialized buffer and spring system for better recoil management.
- Improved Balance: Offers a more balanced recoil impulse for smoother operation.
- Durability: High-quality materials and finishes for long-lasting performance.
- Enhanced Performance: The A5 system allows for fine-tuning, resulting in improved shooting performance.
Applications
The A5 buffer tube is favored for high-performance AR-15 builds, particularly for competitive shooting, tactical operations, and applications where smooth recoil control is essential.
