A Big Salvo and Maverick, to get a sense of size.

The "scope" does not align with the crosshairs. (It's aimed at the bottom of the plastic sheet which has the crosshairs imprinted.) Just thought I'd note that.
It has 2 compartments (one on each side) to hold darts. (frickin' adorable, I know.)

The stock ammunition is worth explaining.
The single large missle is similar to the arrows from a BBB, save it has no fletching(tail fins), but instead has 2 "wings" that project out from the dart head.
The bola-dart is basically the same thing, except split down the middle,with string connecting the two halves. Ideally when fired the 2 parts would fly apart, and giving the round a wider area of effect. Instead the two posts, on which the darts are mounted (like the tek 10, Speedloader, and Secret Shot, for example.) are arranged vertically, completely defeating the purpose, unless one wishes to fire "gangsta" at their foe.
The dart are comparable to tag darts, save they are about 1/8" shorter, and the foam is much more firm.
The blaster's function and operation requires a bit of explanation.
It has 4 barrels, as you can see, and a single trigger. Unfortunately, it has only a single air tank. Which barrel is to be used is determined by a barrel selector. So rather than function like a Big Salvo, it functions more like a Secret Shot powered by pump & tank, rather than spring & piston.
How to select the desired barrel

Notice each muzzle is numbered.

squeezing the trigger advances the dial, the number displayed obviously indicating which barrel is selected. sliding the orange switch (located above, and to the right of the barrel indicator) forward locks the drum, and the chosen barrel is set. Pressing the orange (above, and further to the right) button releases the lock, and a new barrel can be selected by squeezing the trigger.
Onto the internals.


To disconnect the wires, gently pull the junction pieces apart.
The tank, viewed from the behind

Everyone felt the Longshot wasn't complicated enough, right?
I was expecting it to be rather elaborate, seeing as the blaster has a trigger that rotates, and moves away from the pump, tank, and barrels and has to function after relocation.
The trigger relaxed

The trigger being squeezed.

You can see how many parts move just to press the firing pin in, and release the air.
Here are the modifications I performed
The pump was glued shut, I simply cut through it (be careful to not cut too deep, into the pump handle.)
and put a bit of hot glue to plug the pump.

Next was to remove the pegs.


The bottom pair of barrels received PETG barrels cut to length for tag darts. The upper pair received 1/2" PVC couplers. I had to sand the ID of the muzzles, so 3 PETG barrels would fit.
The Finished product

Ranges (20 pumps/shot)
All shots fired level or <5 degrees above the horizon.
Muzzle 1: 3" of 1/2" cpvc barrel. Tag dart. 65feet.
Muzzle 1: 3" of 1/2" cpvc barrel. stock dart. Technically the dart didn't leave the barrel, but the barrel did fly out of the coupler, and landed about 30 feet away.
Muzzle 2: 6" of 1/2" PVC. tag dart. 35 feet.
Muzzles 3 & 4: 3" of PETG. tag darts & stock darts. 35 feet.
I tried pumping the blaster 30 times, and I had to squeeze the trigger about 6 times before it would fire. Its range was also about 65 feet.
The only other modification I considered is to replace the light bulb in the flashlight (the gray box, located above the pump) with multiple LED bulbs, so the flashlight will actually illuminate the other side of a classroom properly.
As complicated as this thing is, I'm sure I left out something minor; feel free to reply or PM with questions.
Thanks for your time.
