I purchased a brand new M&P15 yesterday. Was in the process of zeroing this evening. I had fired 15 rounds over about 15 minutes. When I squeezed the trigger next, the gun blew up, knocking my glasses and earmuffs off, and burning my right forearm. As near as I can figure, the round didn't fully seat and allow the chamber to close BUT the gun fired anyway. Much of the gas blew out through the magazine exploding it into pieces and sending unfired rounds everywhere. It scared the **** out of me. I am an army vet and have never seen anything like this. I'm taking it back to dealer tomorrow and expect he will be helpful, but ***....I don't feel comfortable with another S&W. Will probably just get my money back. Is this a problem with this model or did I just get the one in a million?
First off, I seriously doubt the explosive force of the failure is what knocked your glasses and earmuffs off. Your startle response jerking back of your head and turning away from the threat would have been the cause for that when you had a perfectly natural reaction to an unexpected and sudden occurrence that spewed hot gas and various particles in unexpected directions. Your statement that much of the gas escaped down the magazine well confirms this.
I have been present when something like this has happened a couple of times, and while startling to say the least, does not normally result in serious injury to the shooter. Bystanders to the right of the ejection port are a potentially a different matter.
Firing out of battery can happen with several different designs of autos, Glocks being the brand I have the most personal knowledge of. Particularly in .40 caliber.
