I was testing a Lone Wolf G19 compete frame I had picked up recently here. First time out I had a problem when it doubled, changed the connector and all was well. Then took it to the range, ran 2 mags through it and it functioned perfectly. I had also picked up a threaded barrel made by combat armory. Put it in the lone wolf build and after 2 shots it doubled, then next pull full auto for 3 rounds. Put back the original barrel (not threaded) and it then ran as it should? ??????? Could a barrel swap somehow made this gun go full auto? Either way I am going to change the entire fire control group to be on the safe side.
