This video explains how buffer weights are used to tune commercial rifles, particularly when dealing with ammunition variables and overgassed systems. The instructor details how different buffer weights (H1, H2, H3) can mitigate issues like bolt carrier bounce and fast cycling caused by higher-pressure ammunition, by slowing down the action. He emphasizes that military rifles are designed with known variables, while commercial rifles must accommodate a wider range of ammunition, making buffer tuning a common adjustment.
