You can easily disconnect the auto feature just by taking a hacksaw blade and cutting off the bottom of the the flat rod that actuates the safety. Not reversible!

Rich Cole does not work on the 626/470/471 triggers, and if he doesn't want to work on them, I wouldn't want anyone else, especially Briley, screwing with it. Briley choke tubes and their Thinwall installations are as good as it gets; their gunsmithing; not so much.
