Re: Pulse Rifle - DESTROYED BY UPS!!!
Also, be sure that EVERYONE in the loop realizes and understands that this is a PROP weapon and that none of the components is a firearm in the technical / legal sense. On some prop guns that use a real, workable firearm you need to go through some other hoops to legally ship it (the same as for any other real firearm) and I would want to be sure that someone at UPS does not summarily determine that a "firearm" was illegally shipped (or, two firearms made into one weapon system) and pass it on to the feds and thereby try to void any claims, etc.
I don't recall offhand if a real TSMG and/or real Rem 870 was used in your build. Even if not real, some of Matt's replicas can fool people.
Just want to cover any potential, "Hey, that's a gun...no, it's two guns!" responses by people inspecting the pulse rifle. You may want to keep a picture handy from the movie showing the M41A for the benefit of those who are unaware of what a pulse rifle is, the Aliens movie, etc.
