Love it, but I have to suggest an alternate name.

To me, it seems more like a Reggie Deluxe. In order to understand the reference, you'd have to see Phantasm II, where one of the characters welds two double barrel shotguns side by side.

Oh, there are fans of the Doctor here, I'm sure.

The problem isn't that there aren't fans of Doctor Who here, it's that your thread is lacking in substance.

#1) Photoshop? This could have been done in paint with as much skill.
#2) 'Round here we look for substance, not "hey this would be cool". Besides, all you accomplished was pasting Dalek barrels on Nerf guns, or Nerf darts on Dalek weapons, without even the slightest consideration of whether or not the placement or design was feasible, much less beneficial.
#3) Oh god, your spelling, grammar, punctuation, and general grasp of the English language is atrocious.

Here's an idea for linking the prime, without linking the firing:

Depending on which hand you use the double jolt in, you'll likely fire the barrel on the opposite side first(i.e. Right hand, Left barrel first), but test first to see how your grip/fingers work the triggers.

So what you do is take a piece of brass or aluminum tubing to fit around the T-bar of the priming handle. It should be long enough that it would span both priming handles. Glue one side onto the Priming Handle of the Primary Jolt(the one you would fire first), then cut half of the pipe that would extend over the second handle so that the remaining half is toward the blaster.

Now you should be able to prime both barrels simultaneously by pulling down on the pipe, but when you fire the primary barrel, it is not linked to the secondary barrel.

I hope that is clear without pictures, it's balls-o-clock here and I don't have sufficient energy to put some together.

Hate to burst your bubble, but use the search function, and check the Modifications Directory.

This has been done Double and Triple Turret, and the method is much cleaner.

Umm, what about a dremel for the rail?

You could, but grinding that much with a dremel, you're bound to cause some divots, unless you have a SUPER steady hand. Also, you will make a lot of melting plastic fumes. I'd stand by a file for this.
