In the case of a Remington 700 Action there is a centerline. Every component of the rifle will reference to this centerline. It serves as the centerline of the bolt-way and the centerline of the threads. It should also be the same centerline of the bolt body and the firing pin hole.rom the factory the receivers are threaded 1.0625 X 16 TPI. With a very sharp single point carbide tool I re-cut them to 1.075 X 16 TPI (that s just enough to clean them up completely and establish a new standard). On the same set up the recoil lugs are re-cut and the receiver face is re-cut.
