No-Go Gauge Test on an AK while hot
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.
