This is a strong knex gun. It can shoot anything that fits in the barrel. It uses only basic knex pieces and a good rubber band. If you use blue rods as ammo you will surely get your target. This is my first instructable so be nice.
Step 1: Build the Barrel
This is the barrel. You can make slight modifications depending on the pieces you have. Make it by looking at the picture.
Step 2: Build the Firing Pin
This is a very easy step. Make it by looking at the picture. You just need to tape the part where the orange connector and the grey rod meet.
Step 3: Build the Handle (optional)
You do not have to make the handle but it gives you better grip.
Step 4: Connect Everything
connect all the parts you made made like the picture shows. Also connect the rubber band to the orange connector on the end of the firing pin and the other end to the front of the gun. This is a block trigger so pull back the firing pin the turn the trigger so it covers the hole that the firing comes out of. Then put the ammo in the front of the gun. Now you are ready to fire.
