A-tec Hertz H2 Cal. 223 A-LockH2 is Hertz version 2 and replaces all our Hertz models. In fact it is an upgraded modular Hertz with improved technology, stronger design and and it is very effective on the first round pop/cold barrel shot. The modular design provides the user the option to choose to take off one or two modules for a shorter and more compact design.
