I love this. This guy knows exactly what happened without examining the remanants of the gun or anything.
So we are to accept that a defective barrel was stolen from the Army MTU at Ft. Benning, and made its way to this rifle, I belive in CA, worked fine for XX years, then blew apart like a grenade.
I think this guys theory would have signficantly more credibility if he had said: "This barrel may have been one of a defective batch delivered to the MTU several years ago. We had several that did this due to yadda, yadda, and this type of failure is so rare that it seems it could be from the same cause. If it is one from the batch we encountered, the barrel would be marked with yadda, yadda. The MTU had planned to destroy them but this one must have made it out of the armory some how."
As it is, I can't give this much credabililty. The MTU probably does have more potential for rifle parts to go missing than any other Army organization, so I think it is possible. I just have problems with some one being so certain about something with no first hand knowledge of the incident.
