Well, I finally had some spare time today to begin work on my covenant carbine. I decided to use some 7/8" thick styrofoam insulation as a base. I shrunk down the scale a bit, so that it would'nt look ridiculous, but still look and feel fairly large (42"). I'm basing the design off of a mixture of the game and toy versions, as well as a little of my own. I'll be posting more of my progress soon.
