1. A method for inserting a safety block into a rifle comprising an upper receiver and a lower receiver, the lower receiver comprising a trigger assembly positioned and secured within a cavity of the lower receiver, the method comprising:
moving a takedown pin to an open position;
rotating the upper receiver away from the lower receiver along a pivot pin axis to expose the cavity of the lower receiver;
inserting the safety block into the cavity of the lower receiver to rest against a hammer of the trigger assembly, such that a portion of the safety block protrudes over a top plane of the lower receiver when the safety block is inserted; and
rotating the upper receiver back over the lower receiver, wherein closing the upper receiver brings the upper receiver into contact with the lower receiver and the safety block and rotationally pushes the safety block down and against the hammer, and wherein rotating the safety block against the hammer rotates the hammer such that the hammer is freed from a trigger sear of the trigger assembly.
