This Impressive replica is made of machined aluminum just like the screen used ones. In fact this PPG was built using measurement from an actual HERO. You can't get any more accurate than that. Also came with a very nice plaque and spare power cap.
I was lucky to fine one of this as the maker almost sold them all. he gave me the option of A kit or this built replica that includes real grips and pre-installed red LED that is activated by the trigger. The neat thing is that the gun can be striped and rebuilt.
