This guide details the installation of the A5 Buffer System for the AR-15 platform, drawing on expert insights from Brownells and Sons of Liberty Gun Works. The A5 system, designed to emulate the performance of a rifle-length system in a collapsible stock configuration, offers significant benefits in carrier speed management and recoil reduction. Proper installation requires the specific A5 intermediate receiver extension and a rifle-length spring, as standard carbine components are incompatible. This modification can lead to smoother cycling and increased component longevity.
