Fully Functional LEGO PORTAL Gun

Fully Functional LEGO PORTAL Gun

Here is an epic LEGO Portal gun that is fully functional. The gun took a year to plan, and 3 weeks to build. It has just under 2,000 pieces and has a LEGO Mindstorm controller to help open and close the prongs and turn on the light effects.

Check out the video of the gun in action:
