Well, having the Maxflow as the reg you count on for velocity isn't a bad thing at all really. I NEVER EVER EVER shot hot with my Shocker in the year or so that I had it. If from what I see and interpret from pictures is correct there will be an allen screw in the locking rign to prevent accidental or deliberate on field velocity tampering, so there will be absolutely no reason to have hot shots from it with routine care of the piston.
