An internal reset system for paint ball markers. A hammer body as modified
rearwardly to include an axial opening to receivably retain the forward
head of a reset rod. The forward portion of the reset rod is thus free to
reciprocate within the axial opening, but restrained, during the reset
phase, when the head of the reset rod internally encounters a flange at
the rear of the axial opening. In this phase the reset rod carries the
hammer to the reset position, compressing a spring, where it is retained
by the trigger sear ready for the next firing. The rear end of the reset
rod is affixed to a back block that mechanically connects the modified
hammer assembly and the marker bolt. In one embodiment the hammer is
modified by a hammer sleeve, attached rearwardly to the hammer body and
having an axial opening for the head of the reset rod.
