ABSTRACT:
A hammer mechanism for an automatic gun has a hammer 742 connected to rotate about a pivot rod 741 and the hammer has a firing pin striking surface 743. A strut 750 is connected by a pivot 752 to the remote side of the firing pin striking surface 743 from the hammer pivot 741 and the opposing end of the strut 750 from the hammer is spring biassed to rotate the hammer toward a firing position. The top surface of the strut 753 is arranged to be tangential to a top surface on the hammer defining a radius 744 so as to enable a block 300 of the bolt carrier assembly 3 to ride completely rearwardly of the hammer and not to foul thereupon on its forward portion of the bolt operating cycle.
