Introduction: Knex Plasma Pistol

This is a knex plasma pistol that I made when I was a bit bored a couple of days ago. Please note that the barrel is from knexmaster#1's M47 full-stock shotgun-so don't have a go at me for it. This can be really powerful with the right amount of rubber bands. It uses about 202 pieces.
