Show your fellow cosplayers that you mean business with this DIY Gears Of War replica shotgun, which lets you load actual shells and scare the crap out of anyone suckered in to believing it actually fires live ammo.
Built by Mike Iverson of Blind Squirrel Props, the end result is stunningly realistic, and Mike was kind enough to include exhaustive step by step photos of the process, and basic plans so you can build one of these bad boys for yourself.
Now that's one good looking boomstick!
