Buffer tubes are an essential component of the AR-15 rifle and serve as a crucial link between the lower receiver and the buttstock. They help manage recoil and control the cycling of the rifle. The two primary types of buffer tubes available are Mil-Spec and commercial buffer tubes.
Mil-Spec Buffer Tubes:
Mil-Spec buffer tubes are designed to meet the specifications set forth by the U.S. military for use in their weapons. They are made to a higher standard of quality and consistency, ensuring that they function correctly and can withstand the rigors of military use. Mil-Spec buffer tubes are made from high-quality materials and are subject to strict quality control measures during manufacturing.
Commercial Buffer Tubes:
Commercial buffer tubes are designed for use in commercial rifles and are generally less expensive than Mil-Spec buffer tubes. They are made to a lower standard of quality and are not subject to the same rigorous testing and quality control measures as Mil-Spec buffer tubes. Commercial buffer tubes are often made from less durable materials, which can result in a shorter lifespan and reduced reliability.
Differences between Mil-Spec and Commercial Buffer Tubes:
- Diameter: The most significant difference between Mil-Spec and commercial buffer tubes is the diameter of the tube. Mil-Spec buffer tubes have a diameter of 1.14 inches, while commercial buffer tubes have a diameter of 1.17 inches. This difference means that the two types of buffer tubes are not interchangeable and require different parts for assembly.
- Quality: Mil-Spec buffer tubes are made to a higher standard of quality than commercial buffer tubes. They are subject to more rigorous testing and quality control measures to ensure that they function correctly and can withstand the rigors of military use. Commercial buffer tubes are made to a lower standard of quality and are often less durable than Mil-Spec buffer tubes.
- Price: Commercial buffer tubes are generally less expensive than Mil-Spec buffer tubes due to the lower quality materials and manufacturing standards used in their production. Mil-Spec buffer tubes are made from high-quality materials and subject to more stringent quality control measures, making them more expensive.
Conclusion:
In conclusion, Mil-Spec buffer tubes are made to a higher standard of quality and consistency, ensuring that they function correctly and can withstand the rigors of military use. Commercial buffer tubes, on the other hand, are designed for use in commercial rifles and are generally less expensive than Mil-Spec buffer tubes. The two types of buffer tubes have different diameters and require different parts for assembly. When choosing a buffer tube, it is essential to consider the intended use and choose the one that best fits your needs.
