Hi guys, i’m here to tell with you about some ideas that i have on proton pack particular on GB2 Proton pack.
First piece: Heatsink
I think probably the rounded corners are made after the film.
Here some example:
Hero proton pack:
Semi hero proton pack:
What dou you think about that?
I too noticed this a little while back. Was quite surprised as I thought all GB2 heatsinks were rounded, espicially the resin ones.
But why were rounded? they are more beautiful like in the film! 
Probably because they’re so sharp. I nearly slit my wrist with my first aluminum thrower.
I second that. The corners are pretty sharp.
I wouldn’t be surprised if they rounded them off because someone got scratched up…
So they would’ve filed the corners during or after filming? That’s really interesting. 
I think after the film.
Look this picture to compare the heantsinks.

How you can look in the picture, the gun is the same that you can look at minnesota planet hollywood and the picture is taked from the tribunal scene of GB2.
In the tribunal scene you can see tha square corners of the heatsink, in the minnesota image you can see the rounded corners.
Thats a damn good point. Hmmmmmm.
I think it was changed during filming, museum scenes show some rounded edges on both GB1 refit and GB2 hero packs:
So this 2 versions are accurate! i suppose that they were rounded because they are dangerous for the actors
So my GB2 pack will still be accurate if I don’t file the corners off my heat sink, huh? sigh of relief
