Hmm, set screws on the top AND the bottom.
Are the grips on this of the C96 variety or different?
Lurking here to learn about this blaster.
I still think that WIRED blaster is a stunt casting ...
There's a set screw on the bottom on the FH, rather than thumb screw.
Those pics from the VD show a hole on the top of the FH as well.
