HarryAlonzo has pointed out a great rear sight setup. You will have to purchase separately the accompanying longer screw to install it. To answer your question, it's not always necessary to remove the bolt assembly from the receiver to push out the retaining pin for the bolt's manual safety, but...Should you have a fitment problem with the safety hole and the rear sight installation, it's better and much easier to work with the bolt out of the receiver.
Edit - Be careful when removing the manual safety from the bolt. Take precautions to avoid losing the detent ball or even its spring. They are very, very small sized parts installed under that spring tension. Just ask any of the guys here that suffered that fate.
