Toy shot gun for Friday night Arisia?

OK. I'm running out of time to do stuff. I need to have something that looks like a shotgun for the Repo screening/Naughty Nurse sketch [I'm going as one of the Largo family femme fatale body guards]. I had thought to construct one out of paper towel/wrapping paper tubes, but I don't have the time to give it the attention it deserves. So, if there's anyone out here who has something that will pass for this and is willing to let me borrow, do let me know. Thanks in advance.
ETA: buxom_bey  has solved the problem. It's worth 20 bucks to not have to think about this anymore.
