Ho boy...that's a toughie. IIRC, the Missile was similar to the Sapphire Zone (and the Parker Bohn MVP), but the cover was tweaked for more length. About the closest thing that I could think of in the current Big B line is the Monster Bruiser, but the Bruiser has a stronger cover and a higher RG core.
I seem to recall that someone on this site was selling a Missile not long ago. There may also still be a few out on eBay. Worth a look, perhaps.
Hope this helps.
