Check My K.B.K too!

It's obviously a crossbow and it shoots about 65-80 ft.
It might take a while to recreate it, but believe me, it's worth building because of 3 things:

-You get recoil.

-It can pierce a bucket from a distance of around 6 ft.

-It's astoundingly accurate.

Downside is, it's a pain to put together because of the heavy concentration of parts in small places.

Step 1: Accuracy Tips

This part is for more accurate shots.

Step 2: Handle

For better grip, reasons can not be any clearer.

Step 3: Trigger

This one is required for building the firing assembly. Durp.

Step 4: Strength Bars

This part is to make your gun more powerful, and structularly more solid.

Build it twice.

Step 5: Handle Bar (Optional)

This part is optional. It only allows for a more comfortable shot.

Build it four times.

Step 6: Stock

More or less a stock for people with short arms. It just made the gun look better, and be more structularly sound.

Step 7: The Bow

The bow, not much else to it.

Step 8: The Barrel + Strength Bottom Part

The most time-consuming part of the build, but it's needed.

Picture 1-,2-,7- are the same.

Picture 3-,6- are the same too.

Picture 4-,5- are the same aswell.

Step 10: Stringing the Rubber Bands

Pic 1: Put the rubberband at the back of the trigger and, then put them under the blue rod that hasn't been used. String it to the front end of the gun, where possible.

Pic 2: String six rubberbands at the front, as seen in the pic.

Info: NEVER, I repeat NEVER pull all rubberbands at once.
Do them two by two if, you want to have all your fingers still intact :D.
