What engineers do in their spare time

As many of you may know I participate in hvz which is essentially a glorified reason for college kids to play tag. Zombies try to infect humans, who carry Nerf boasters as their line of defense. Last semester I survived, but with little style. For this semester I pulled out the stops and decided to make this, which I affectionately named Order. The blaster is a rapidstrike with a camera bipod and drum magazine as well as an extended barrel as my suite of attachments, which leaves it only a couple of inches shorter than the longest stock Nerf blaster... Zombies, your days are numbered!
