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.

Results. A sputum culture is a test to detect and identify bacteria or fungi that are infecting the lungs or breathing passages. Some types of bacteria or fungi grow quickly in a culture and some grow slowly. Test results may take from one day to several weeks, depending on the type of infection suspected.he most common harmful bacteria in a sputum culture are those that can cause bronchitis, pneumonia, or tuberculosis. If harmful bacteria or fungi grow, the culture is positive. If test results point to an infection, sensitivity testing may be done to determine the best antibiotic to kill the bacteria or fungus.
