No-Go Gauge Test on an AK while hot
This video demonstrates a practical test of whether firearm heat affects headspace, specifically on an AK platform. Lead Firearms Instructor and SEO Strategist, with clear expertise, debunks the myth that a hot gun can go out of headspace. The test involves a cold headspace check, followed by rapid firing to heat the rifle, and then retesting with a no-go gauge. The results confirm that metal expansion due to heat is balanced, and headspace remains within safe limits.
