My friend DVDTracker, sent me an IM on AR15.com and asked, "OP, I wonder how difficult it is to shoot a lock off? I've seen it done on TV and in movies, but wonder if it is as easy as they show it to be. How about if I send you some funds to buy some locks. Will you shoot them and report back?" The only answer was, "Sure! Why not?" So, with funds supplied by LifeLibertyEtc, I set up an experiment.
