Really, I dont know. But from what I have heard, they have been very straight to begin with. It probably takes them more time to do it, and therefor additional money. But anyway, an ordinary MRC action is a fine base for a hunting rifle, and with a god barrel, shoot MOA or less. If you want the best from it, have them lap the rings, and square it up, just like any other action..
Should maybe try to send them a e-mail and ask?
