I've probably got one of the best ones yet....so, my dad had an M2 carbine....had it for soo long that it was "o.k."(well probably NOT)....BUT he had it forever....he got scared when he got his FFL...was afraid he would get "inspected" one day, and they might find it....never occurred to him to place in my safe keeping.....so, he made the attempt to remove the full auto part....not a very good idea as most of the parts, held together by springs and what not exploded on him....he was not able to collect all the pieces....M2...GONE...converted into an M1 in nano seconds...
it was fun to shoot...
