This video delves into the G36 controversy, explaining how differential heating of its polymer receiver could affect the embedded steel trunnion and shift point of impact. Despite media sensationalism, the G36's performance is analyzed objectively, with expert Ian McCollum highlighting that all firearms experience accuracy degradation when hot. The discussion covers historical context, legal battles, and modern adaptations addressing heat concerns in military rifles.

This guide details a technique for testing the headspace of an AK-pattern rifle after rapid firing, as demonstrated by an expert instructor from Military Arms Channel. The process involves performing initial cold headspace checks with go and no-go gauges, followed by rapid firing to heat the weapon. The crucial step is re-testing with a no-go gauge while the firearm is hot to determine if heat expansion affects chamber dimensions enough to compromise safety. The expert emphasizes that proper firearm maintenance and immediate attention to any failed headspace test are critical for safe operation.
