Damnit, you beat me to it!
I was planning on doing something similar with a broken Zapper and an old CF's internals. (I've also thought about placing BBBB internals into the shell of a Super Scope)

Still, I'll agree with NerfMonkey and Carbon on this one; It IS fucking awesome.

This is the only mod I've seen that allows you to use both the multi-barrel "shotgun" and a traditional 12" PVC barrel. Quite versatile!
Although, some of the pics are really blurry.

It's been done before:

I wouldn't mind seeing the Supermaxx series again, those were some pretty sweet guns.

So tomorrow's the big day, I'll be hosting a small Nerf War for my hometown in Ft. Worth Texas.

Damn, if you had waited one week I could've been there. Oh well...

Recommendations for rules:
* (this was someone else's idea) If you're afraid to shoot yourself at point-blank with it, don't use it
* Nerf guns that look like real guns should not be used for obvious reasons
* Try not to Nerf around popular and or crowded places (a bit of a no-brainer, though), there should never be an opportunity for a non-nerfer to be hit by stray fire
* Make sure to have craploads of ammo avaliable, if possible (otherwise, most of your time will be spent searching for fired darts)
* "Death" or "S.n.!.p.e.r" darts (stefans made with air restrictor parts or thumbtacks instead of hot glue or felt tips) can cause bodily harm (as in, more than bruises and welts); those who choose to use them should be banned
* Eye protection should be mandantory; in the heat of (foamy) battle, people accidentally shoot people in the head far more often than you think
* Have fun (another no-brainer)
Of course, these are recommendations, you don't have to use them.

For gametypes, however, anything goes. I suggest CTF (a mainstay in any psuedo-combat simulation), Humans vs. Zombies (one person is the Alpha Zombie; anyone a zombie tags becomes a zombie, and looses the ability to use their weapons. Zombies win if all humans are zombified, humans win if all zombies are eliminated), and VIP (two teams, one person is the VIP; team "A" has to protect the VIP for "x" ammount of time, team "B" has to either eliminate the VIP, or take him hostage)
Anything with an objective can be used as a gametype. Therefore, be creative!
