From what I gather, the video relays experience based on a specific model(s) of rifle that already had the most important aspect, gas port size, predetermined. For civilian purchasers who can acquire rifles with “more correct” (based on a different spectrum of use and potentially different gas system length) gas port sizes, buffers can be used a little differently. What Bartocci says makes sense to me; however, as non-military users, we have more broad options that do not require such a rigid view of the buffer’s role.
