Do not return to the range with that thing until you get it fixed. At least twice I've read of guys who got in dutch with the feds because their guns did exactly what yours did. Even though both were genuine malfunctions caused by mechanical failures, not garage tinkering, the feds came down hard on the owners. Even if you don't end up in the pokey, you probably will lose the rifle, and spend money on lawyers, if they get involved.
