You know what Jwraps, this might sound a little peculiar, but the Call of Duty series has a ton of "weapon camos" that dress a gun up just like a Jwrap would dress a
mod up. Here are a few for example:
Art of War:
Cherry Blossom:
Ronin:
Pack a Punch:
I would pay top dollar for a textured Pack a Punch wrap. In the Zombies mini-game that comes with Call of Duty, if you place a normal weapon inside a Pack-a-Punch Machine, it'll spit out an upgraded version of that weapon with that camo on it. Bare with me, for example:
Ahhhhhhhhh! That would look so nice on a
mod!
