This video details a heat torture test on a Zenit rail system for AKM/AK74 platforms. After firing 90 rounds of 7.62x39mm ammunition rapidly, the rail remained comfortable to touch, indicating effective heat dissipation. Accessories like an Inforce light and Bushnell TRS-25 red dot also survived the test without issue, though the rifle's gas block and barrel reached temperatures of 300-400°F.
