My friend was telling me about a guy they go shooting with that can stiff
arm most rifles and get them to fire like an auto. He holds his trigger
finger still and pulls the trigger up against it, recoil makes his finger
release the trigger and his other arm is pulling the trigger back to his
finger.

An article on "bump stocks" just ran in my local paper:

http://news.yahoo.com/add-ons-let-se...201305718.html

"A bump stock fits over a rifle's "buffer tube," replacing the gun's
shoulder rest. A "support step" attached to the pistol grip partially
covers the trigger opening, preventing contact with the finger. By
holding the pistol grip with one hand and pushing forward on the barrel
with the other, the finger comes in contact with the trigger. The
recoil causes the gun to buck back and forth, "bumping" the trigger..."
