A properly cleaned M-16 won’t. A dirty bolt/firing pin may have crud which presses the firing pin forward. Most generals have an aid or batman to do the cleaning part.
To what are you referring? Are you saying that a properly cleaned M-16 won't fire if dropped on its muzzle from ten feet onto concrete?
Or are you suggesting that the General's rifle, if properly cleaned, and assuming the chambered round doesn't have a high primer, would not fire on chambering?
