Hello, redstoners, my name is UnderscoreZero. Today I'm gonna show you how to make a fast auto-fire dispenser :D This is my design, but someone else might have though of it before.

You will need:
1 dispenser
1 redstone dust
1 lever
2 redstone torches
2 solid blocks
Arrows

Step 1.
Place your dispenser and fill it with arrows.

Step 2.
Place a lever on it's face and some redstone ontop. Hold shift to place blocks on dispensers/chests etc.

Step 3.
On both sides of the dispenser place the redstone torches.

Step 4.
Turn the lever on, then place the blocks ontop of the torches.

Step 5.
Turn the lever off, and have fun!
