That's pretty cool. I bet you could squeeze more range out of it if you sacrificed the deployability and made the powerstock longer, and put in a piece of [k26] or something.
But this is pretty cool that you were able to do that while still keeping it collapsible.
I really don't like the sounds of this, even if half this is true. It's probably just all speculation, but seriously? Tactical Shield? The fact that it takes 6 D batteries makes it likely too bulky to use in a war, and it most likely won't shoot far, likely operating on gears pulling back the plunger, therefore requiring a pretty weak spring as to not break the gears.
Damn it's been a while....
This thing looks friggin amazing.
SgNerf: I was wondering if you could give us an idea of the size of the plunger tube. Is it similar to a longshot's? It looks smaller to me, but it's hard to tell, not having anything familiar for reference.
I may start up again, just to use this thing.
