New guns jamming in combat!

I hear the SAW was having major issues in Iraq. Not only did it jam a lot (To the point where it needed disassembly in the middle of combat to clear it!!!), but that the barrels frequently warped. I bet this is the gun if I had to guess. I know that a typical SAW user carries 3 barrels into combat now - sad.

I have the Barrett 468 upper conversion. I just attach it to an AR-15 lower. I've probably put 800 rnds thru it and haven't had any problem.
