To remove the bolt from a Colt Sauer rifle, first ensure the rifle is unloaded and pointed in a safe direction. Open the bolt by pulling it to the rear, then locate the bolt release lever, typically located on the right side of the receiver. Depress the lever while simultaneously pulling the bolt fully to the rear to release it from the action. Once released, you can lift the bolt out of the receiver.
