It turns out the magstrike pump fits right in to the pipe for the mega-missle, and all that was left to do was seal it up with some hot glue. The integration into the BBB body to make it more wieldy was more of a chore. I made this with minimal dremmeling and a cut up missle from the buzzbee gun.
The barrel is a cheap crayola marker knock-off, and it simply shoved into place and held with some electrical tape. The PVC over it just looks cool. The trigger is scrounged together from some metal bits, a paper clip, the old buzzbee trigger, and some plumber's goop.
As you can see, I use the WHOLE magstrike pump in the mod, which means it only needs about 5-8 pumps to reach a good capacity to fire a dart nice and fast. A single pump can actually give me competent distances of maybe around 30 feet with more or less angling, and can be nearly silent with the right dart (stefans make more noise, it seems). It can go up to about 15 or 20 pumps before it won't take in any more air, and it makes a nice big POP noise when fired. At the capacity, stefans travel VERY fast, but anything else tends to spin out of control and reduce range.
I have no official measurements, since I don't have the tools for it, but an occassional 100+ range with stefans wouldn't surprise me. It can fire across the entire student lounge in one of the dorms, which is a big room mind you, I'd give it at least 50-60 feet, and still smack into the opposite wall really hard.
Plus the gun is very comfortable, which was the whole point of sticking it inside the BBB shell.
