Why would you want to remove it? It ain't there for looks. If the firing pin or spring break thats the tool you'd need to replace them. With the bolt closed and cocked, turn the safety up to it's middle position so you can still open the bolt, now remove the bolt from the rifle and unscrew the rear section, insert the firing pin in the hole, now grasp the bolt shroud with your thumb hooked over the safety lever and press down on the shroud far enough to turn the cocking piece 90 degrees in either direction and seperate it from the firing pin without releasing downward pressure on the shroud. Once the cocking piece is off slowly let the pressure off the spring. Now you can seperate the pin and spring from the shroud for replacement or cleaning. To reassemble, repeat the process in reverse. WARNING, a spring in good shape requires about 30lbs. of pressure to compress it so don't let the shroud slip. That 30 lbs. is plenty enough force to send the shroud flying with the potential for injury to you or bystanders.
