A three-position firearm safety mechanism has bolt lock arm, user-operated lever and sear safety arm including inner eccentric end members interconnected by a trigger assembly pin, with the lower blade-like end of the lever slidably received within an outwardly facing channel on the sear safety arm and having a boss connected to an offset eccentric aperture in the lower arm, to permit the bolt lock arm to be temporarily disengaged from the bolt notch by depressing the lever against a spring bias while the safety is rotated to the firearm “safe”position.

In a safety mechanism for a firearm having a bolt including a slidable firing pin, a trigger housing, a sear movably mounted to said trigger housing for controlling the firing of said firing pin, and a safety pivotally mounted to said trigger housing for rotation about a pivot pin by means of manually induced pivotal movement of a lever arm portion of said safety between a “safe”position, in which a bolt lock arm portion of said safety is brought into bolt movement blocking position and an inner arm portion of said safety is brought into sear movement blocking position, and a “fire”position, in which movement of said bolt and sear are unobstructed by said safety, the improvement comprising: means, responsive to translational movement of said lever arm portion while said safety is in said “safe”position, to temporarily back said bolt lock arm portion out of said bolt movement blocking position while said inner arm portion remains in said sear movement blocking position, whereby said bolt can be withdrawn without pivoting said safety toward said “fire”position.
