Read the review!
That's right, a pistol that is truely rifled. It's a single shot, because single shots are the most powerful type of gun, second only to slingshots.
What is a rifle?
A rifle is a gun, traditionally a large weapon, like a sniper rifle. The barrel is constructed so the bullet will spin as it leaves, greatly improving accuracy and range.
How the heck does the Tempest work then?
Well, at the moment it is only a single shot, but it's really a case of one shot = one kill! A bendy rod is clipped onto the nozzle of the pistol, which causes the ammo to spin as it leaves. It is technically part of the barrel, as the firing pin runs alongside it.
But what if I don't have a bendy rod?
Don't worry, this pistol functions excellently as a regular gun, and it even has a seperate bullet lock for the benefit of those who don't have flexi rods. The flexi rod required is the length of a grey rod.

Step 1: Main Gun
First the internals, then the plates. Simple.
In picture 1, you should see a part made of 3 orange connectors with tape round the top one. It should only be wrapped round twice, maybe three times. It's a low friction bullet lock.
Also in picture one, the handle has two whites not connected to anything, two greens not connected to anything and another two whites not connected to anything. There should be three in each row, not two, I never realised until after I took the photo of the error!
Last picture it shows the grips on the handle (which you made in picture 1). Ignore the pin, I'll explain that in the next step.
Step 2: Finalise
2) Bands, I use 8 size 63s, (new), but just load as many as your muscles can pull back! The ram can take a virtually limitless load, and the gun is designed so the trigger or body won't get damaged by too much power when it is cocked/fired (why it's quite chunky).
3) IT IS ABOSOLUTELY MEGA IMPORTANT THAT YOU USE A BLACK ROD FOR MAX POWER
To make the pin:
First, covert it all in tape (preferably electrical, but it doesn't matter)
Add a nice thick band (around the vicinity of size 63 or 64) to act as a shock absorber. This means that the pin can take nearly limitless power, but the shock absorber needs to be wound fatter by the bit of the pin head that slams into the back of the gun. For some people it may take a while to get this perfect, but it's fairly easy.
Step 3: Firing
Well I hope you know how to fire a normal k'nex pistol, because this rifled pistol works the same way!
In the picture, There are the best bullets to use for the rifle. I would recommend Cannon ammo for a war.
Load two green rods into the gun. Shotguns are smoothbore, so remove the flexy rod. Now you can use the might of the cannon ammo!
The Cannon ammo can only be used in smoothbore mode, see the next step for details.
Step 4: Last But Not Least...
Well congratulations: you have just made your very own tempest pistol! Comment below with a picture of yours on this step, and I'll add it to the instructable!
The only problem I have with this gun is that it can't fire cannon ammo in rifle mode. I am working on this right now.
And finally, show me some mods! If I like them, I'll take note of them, and together we'll make version two!
