Yup . Total destruction. Blew the left and right side of the upper to pieces and the Picaninnany rail on the top buckled. Magazine blew out the bottom. Called the manufacturer and they want it back. I'm sure I'm not going to get anything out of it. Maybe it will give them info so someone else will benefit. No injuries but man oh man pieces went everywhere. On the phone they felt it was due to case failure . We'll see what the say after they tear it apart. They did want to know if I crimped or not. And the answer is no I don't. I think I'm done with the rattle guns. About $1300 to 1500 gone. -O,- Be careful guys.
