The barrel burst on the RI, first round using factory ammo. Was not a good day to say the least.
Had a Colt 1911 do that to me in the Marines. DS/DS vet here and had 1911 Colt's with jamming issues. But heck I never had a issue with M16-A1's and A-2's while in service. I know alot of Vietnam vets will tell you a different story. But M16-A1's issued at first in Vietnam did not come with a cleaning kit (yet people tell you to only buy Colt AR's hmmm?). I know your barrel burst had noting to do with cleaning. Just showing you can have issues with the "Good Guns".
