Gorse speaks the truth. I have talked to Remington several times and gotten the same story. They have this 700 action production down to a ruthlessly efficient process. The make only two action and two bolts. The bolt heads (I think there are five now) are made separately, and silver soldered into the bolt bodies. I have built several bench rest rifles on the cheapest 700 action (ADL), and after truing and lapping, they shoot one hole.
