How Much Does a POF Buffer Tube Weigh?

Published in Firearm Components 2 mins read

A POF (Patriot Ordnance Factory) buffer tube weighs 4.6 ounces.

Understanding AR-Platform Buffer Tubes

The buffer tube, also known as the receiver extension, is a crucial component of AR-platform firearms. It houses the buffer and recoil spring, which are essential for the rifle's cycling mechanism. The buffer tube also serves as the attachment point for the buttstock, providing the structural foundation for the shooter's interface with the firearm. Its design and material significantly influence the weapon's overall balance, recoil management, and reliability.

POF Buffer Tube Specifics

The specific POF buffer tube referenced has a total weight of 4.6 ounces. It measures 3.25 inches in length. This compact size and specific weight contribute to the overall feel and function of a firearm utilizing this component.

Factors Affecting Buffer Tube Weight

The weight of a buffer tube can vary based on several factors:

  • Material: Most buffer tubes are made from aluminum alloys, with variations in specific grades and manufacturing processes affecting density and strength.
  • Type: There are generally two main types:
    • Mil-Spec: Manufactured to military specifications, typically with a smaller outer diameter (1.148 inches).
    • Commercial-Spec: Slightly larger outer diameter (1.170 inches) and often a slanted rear end.
    • While the POF tube mentioned is specific, the distinction between mil-spec and commercial can sometimes affect material thickness and thus weight.
  • Design and Length: Different buffer tube designs exist for various applications, such as fixed stock configurations or collapsible stock systems. Longer or shorter tubes, or those with unique internal or external features, will naturally have different weights.
  • Integrated Features: Some buffer tubes may integrate sling mounts or other features, which can add minimal weight.

Importance of Buffer Tube Weight

The weight of the buffer tube, though seemingly minor, plays a role in the overall balance and feel of an AR-platform rifle. A lighter buffer tube can contribute to a lighter overall firearm, which is beneficial for portability and maneuverability. Conversely, a slightly heavier tube might shift the center of gravity rearward, potentially influencing perceived balance, especially when combined with different buttstock weights. Ultimately, firearm enthusiasts often select components to achieve a desired balance and performance profile.
