Having said that, I can't understand why no one here is concerned they may be reloaded. The tube is just the aiming device. I have no doubt that there are some enterprising Jihadists that have made rockets that will fit the tube. Maybe time to look in the Anarchists Cook Book again for updates.
As a peice of expended ordnance, the AT4 launcher is demilled by the Army (or a contractor) before being released fore sale to a scrap/surplus dealer. The mechanical acutuating mechanism is removed and certain locations of the launcher are cut to render the tube pretty much worhtless. While I am certain a good ordnance man can get a demilled copy back into useable condition, the rockets are rather hard to obtain outide complete AT4 munitions, so outside of some machine shop and homemade explosives, it is an unrestricted curio.
