I bought a reinforced one after the stock one broke, and this has cracks on it now too. The piston head came with the piston, aluminum. And no, haven't been doing an excessive amount of dry firing. I mean, it happens a few times per game, but nothing out of the ordinary.
I think it would be beautiful if someone could build a metal/rubber hybrid mechbox. Everything metal but the front end (part that usually breaks) being made of a slightly stretchy hard rubber. Hard enough to hold your mechbox stuff in place, but soft enough that it won't break and can absorb some of that piston shock.
