A surgical loading unit for use with a handle assembly includes an elongate outer frame defining a longitudinal axis and having proximal and distal ends, an end effector mounted to the distal end of the outer frame, a drive at least partially disposed within the outer frame and operatively coupled to the end effector, and being adapted for longitudinal movement through a plurality of sequential firing strokes to operate the end effector and a rotatable counter mounted to the outer frame. The rotatable counter is adapted for rotational movement through an arc segment of rotation upon movement of the drive through each firing stroke, and has visual indicators for providing visual indicia corresponding to a number of firing strokes completed by the drive.
