AR-15 buffers and buffer tubes are used to support the cycling system and rear-end setup of compatible AR-15 rifles. The buffer helps manage bolt movement during firing, while the buffer tube houses the buffer and spring and provides the mounting point for a stock or brace. Different buffer and tube configurations can affect recoil feel, compatibility, stock fitment, and overall rifle function depending on the build. This category includes AR-15 buffers and buffer tubes built for proper fit, dependable function, and practical everyday performance.
