ULTIMATE AR-22 MELTDOWN!
This AR-22 "meltdown" test pushed a CMMG upper with a KGmade Swarm suppressor to its limits using Federal Auto Match ammo. Despite reaching high temperatures (barrel 334°F, suppressor 304°F) after nearly 2,200 rounds, the primary failures were due to carbon and lead fouling, not thermal breakdown. A thorough cleaning restored full reliability, demonstrating that .22 LR fouling, not heat, is the limiting factor for sustained full-auto fire in this platform.
