On the RAW rifles who does custom tuning on them?
Tuning? Why would you want someone messing with these? About the only thing you might want to do is make a minor adjustment to the velocity, and you can do that yourself. I would be hard pressed to send a rifle of this caliber (no pun intended) to any tuner, regardless of his reputation. If, in the most unlikely event, that there is something wrong with it, send it back to Martin and he will fix it. I would smite the hand that touched my rifle.
