What is an AR15 buffer and why is it important?

The buffer, located within the buffer tube of your AR15, works with the buffer spring to absorb the rearward energy of the bolt carrier group (BCG) after a round is fired. It decelerates the BCG and then pushes it forward to chamber a new round. This is vital for recoil management, reliable cycling, component longevity by absorbing impact, and consistent weapon operation. Without a correctly chosen buffer, an AR15 can exhibit excessive recoil, violent cycling, and malfunctions like failure to extract, eject, or feed.
