My first reaction wasn't to get mad,
just a little discouraged. Its not
every day you spend over a $1500.00 on a weapon and its
accessories and only have it for 2-1/2 week and have it break.
Later when I could feel the powder burns on my face I was very
grateful to have not been injured any worse. My wife told me about
it, asking me if I saw all of the dust come up but I really didn't
see that.
It appears that when it fired it
ejected the spent case. At the same time it must have blown a lot
of gas pressure back and split the bolt carrier down one side on
the bottom. This caused the bolt carrier to take a small chunk out
my USGI 30 round magazine as it went back. Thus not allowing
another round to be fed into the chamber. Now the bolt and carrier
are stuck in the rifle in such a way that I cannot take the upper
and lower apart. So now it is dead.

I purchased this rifle about 17
days ago and I have shot a total of 264 rounds through this rifle
on three separate occasions with out a single misfire. I was
shooting Remington 55-grain FMJ bullets. This is my third AR and
so far I have been pleased with it until today.
The rifle, as stated before was
an Olympic Arms CAR97 and the ammo was Remington 55gr FMJ
purchased from Cabalas about a month ago. I know that there
wasn't a bullet stuck in the bore as I was sighting in my scope
and watching each shot. By the way I had 3/8" groups at 100 yard
when this happened.
