A buffer tube, also known as a receiver extension, is an essential

component of a firearm’s operating system, specifically in

semi-automatic and fully automatic rifles. It is a cylindrical tube that is typically made of aluminum or polymer and is attached

to the rear of the rifle’s lower receiver.

The primary function of a buffer tube is to house the recoil buffer

and action spring, which work together to control the cycling

of the firearm’s bolt carrier group. When a round is fired, the bolt carrier moves rearward against the buffer, compressing the

action spring. As the bolt carrier returns to its forward position, the energy stored in the compressed spring pushes it forward,

chambering the next round.

Buffer tubes come in different lengths, diameters, and configurations,

depending on the firearm platform and its intended use.

The most common types are the mil-spec (military specification)

and commercial buffer tubes. Mil-spec tubes have a diameter

of 1.14 inches and are known for their standardized dimensions, allowing for interchangeability of various stocks and

accessories. Commercial buffer tubes, on the other hand, have a slightly larger diameter of 1.17 inches and are often

proprietary to specific manufacturers.

Buffer tubes also play a vital role in stock attachment. They feature a threaded end

where the stock is mounted, either with a

castle nut or a locking ring, ensuring a secure connection. Stocks can vary in

design, providing different lengths of pull and

ergonomic features to suit the shooter’s preferences. ar15 pistol buffer tube  | ar 15 buffer spring.

Additionally, buffer tubes may have a variety of additional features. Some

models include a built-in sling attachment point,

while others incorporate a storage compartment for small tools or batteries. Some buffer tubes are also designed to

accommodate adjustable stocks, allowing users to customize the length of pull to their liking.

It’s worth noting that the classification and regulation of buffer tubes may vary depending on the jurisdiction. In some regions,

certain buffer tube configurations may

be subject to specific laws and restrictions.

Overall, buffer tubes are a crucial component in the operation and

customization of modern rifles. Their primary purpose is to

house the recoil buffer and action spring, ensuring reliable

cycling of the firearm’s action. With their various sizes,

configurations, and compatibility, buffer tubes offer versatility and customization options to firearm enthusiasts and professionals alike.
