I'm a bit gob stoppered by the AK but I can't see what role the Regulator would fill. I know I'm going way out there on the AK and won't actually have a use for it but I see even less use for the Regulator. A guard so I can't choke up on it,a swedge to tear up a baton, I dunno. I don't see anything that calls to me here. It should be able to drill well? I'm a new Dog, don't beat me much please.
