A surgical loading unit for use with a handle assembly includes an elongate outer frame, an end effector mounted to a 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 and adapted for rotational movement about the longitudinal axis. The rotatable counter has visual indicators for providing visual indicia corresponding to a number of firing strokes completed by the drive. A counter actuator is mounted to the drive and dimensioned to engage the rotatable counter to cause rotational movement of the rotatable counter through an arc segment of rotation during each firing stroke of the drive. A cam actuator is mounted to the drive and dimensioned to operatively engage the counter actuator to cause release of the counter actuator from the rotatable counter upon longitudinal movement of the drive through each successive return stroke.
