I was thinking, after having the thunderstrike apart here:
That it could be a very workable, light, and cool looking cosplay vera base.
Here is a slapdash paste up of what I was thinking in terms of building:
Obviously the add-ons would have to be custom, but i think its quite possible.
With the way the magazines come apart, you could even construct a magazine with shells inside it.
I think it would be a nice light cosplay vera. I don't costume, but I have some friends who do, and I know they always want light options for the weapons they will be carrying around for hours.
Just a thought.
