This is one of many full, close to 1:1 scale halo weapons I have made. You can actually hold this spartan laser like you would in the game. Also i'm pretty sure that I am the first one to post a full scale spartan laser on MOCpages. :) Enjoy.
I have also included building instructions for this model.
P.S. for those who want to know this is not the halo 3 version of the laser. This is the reach version.
