Abstract: A method for inserting a safety block into a rifle comprising upper and lower receivers, the lower receiver comprising a trigger assembly positioned within a cavity. The method includes separating the upper receiver and the lower receiver to expose the lower receiver and inserting the safety block into the cavity. The safety block comprises a hammer cavity that surrounds the trigger assembly such that the safety block surrounds at least a hammer of the trigger assembly. A hammer stop of the safety block rests against the hammer. The upper receiver is then closed against the lower receiver.
