I ran one on a shot timer at .016 between shots. That said a AR gold was .014 IIRC at half the cost and a lighter trigger pull.
It's a work of art, don't get me wrong about that but the "3rd mode" is unnecessary and it was over hyped with a expert shooter who was used to that trigger. Real world it takes some mags to get used to and consistent strings are hard to pull off, It is not a replacement for full auto or even the slide fire if you just want rounds down range fast. It does double and triple like a champ though, I am much faster with doubles vs a standard trigger.
It's not worth $550 IIRC, its a $250 trigger at best. If your going from a GI trigger you will be impressed but if you have anything other than a cheap two stage you will be disappointed.
