If you are lucky, it's the ammo. Seen it a bunch. Trained the 82nd ABN for three months a couple years back. They were force fed British 5.56. Horrible quality control compared to M855. Hundreds of 'Failure to Extracts'.
Had a guy chamber a Jolly Rancher candy wrapper once and couldn't for the life of me figure out why so many failure to extract until deductive reasoning kicked in and I pulled the wrapper out w/ a a dental tool.
