Fabulous Killjoy (MCR) rayguns?

When the album first came out, they had a limited addition ray gun box set with the cd, bracelet, one of hte four ray guns and killjoy mask. I am making one out of wood carving it and it's a pain. I know some people go with like you mentioned a water gun kinda thing. I know that there is a betterlivingindustry site that sells them but they're hella expensive and I think sold out. Other than that, I think that they don't have any up for sale anywhere.
