Hi gunbugs, a quick and easy indicator, for Allen, of what might, or might not have happened would be a quick look at the rear of the breechblock for firing pin and retainer damage at the rear of the block? With the ejector retainer broken out, it is almost certain that the retainer area at the rear of the breechblock is damaged severely as well... If no damage there, then the ejector area failed mechanically with something causing it to exceed it's yield strength??? Best, til....lat'r.....GT...
