PTS PDR-C Grip Extension
The PDR-C was conceptualized for low profile conceal carry of a personal defense machine gun. In order to not "print" or stick or poke out from under a jacket, the exterior shape was made so that there are no protrusions. This led to the compact hand grip size that compromised comfort. The PDR-C grip extension that allows for a more comfortable full size grip as well as larger AEG battery capacity.
