pitdogboy,
Yea, I've had a jam. It was a fail to extact. I have about 9K through mine and got a jam at about the 6 k mark. Bad thing was I didn't know what to do out of shock. I was more interested in seeing why than clearing it because it has only happened once.
One jam in over 9000 rounds of various types, reloads ect. Not too many guns that can do that.
