AR buffer tubes are used to house the buffer and buffer spring on compatible AR-platform rifles while also providing the mounting point for a stock or brace. They play an important role in the cycling system, overall fit, and rear-end configuration of the firearm during builds, repairs, and upgrades. Different buffer tube styles can affect compatibility, stock fitment, length, and overall setup depending on the rifle configuration. This category includes AR buffer tubes built for proper fit, dependable function, and practical everyday performance.
