Art... There in lies the trouble with matching screen used guns. They are all different in their own way, if you diodn't know the aluminum shrouds for the hero guns were all hand hammered aluminum. As such each one has minute differences from the other. The original gun in the pic you provided was not the one we patterned from.
HCG owns one of the hero guns, all the dimensions came directly form it.
The same speculations could be made comparing three screen used guns.
The HCG shrouds differ from mine in a number of ways and yes it is a matter of how the pictures appear... angle lighting etc.
The HCG shrouds are wider, shorter and not quite as long as mine, the mag well is almost a good half inch more forward, the chamfer around the GL trigger is deeper.
The mag base is thinner, and the forward section of the carry handle is shaped differently and angled back more. There is less of it sticking out the back and the rear straps are narrower.
I'm not sure what posting side by sides with it and my guns will achieve really.
No one is trying to pull a fast one if that's what you are thinking. If the new shrouds can be faulted at all they are a bit too clean compared to the original hand hammered pieces. To be honest if we replicated the HCG gun directly from a hero gun it would look pretty shabby.
