This Q&A session addresses common AR-15 tuning issues, particularly over-gassing by manufacturers. The expert explains that manufacturers over-gas to accommodate a wide variety of ammunition, but this can lead to reliability problems, especially with suppressed or short-barreled rifles. Tuning involves adjusting buffer and spring weights, but optimal reliability is best achieved by selecting a specific ammunition type and tuning the system to it. The discussion also touches on LMT enhanced bolts, gas system lengths, and the nuances of polygonal rifling.
