ray gun-worth the donuts?

The non destroyed gun produces 1 ammo every 8 hours if it's out in your town, the destroyed gun out in your town means you can task Kodos (so place both out in town, as of 1pm eastern, there's no countdown timer to next ammo arrival)You can tell when it's arrived by a big ammo chunk floating on top of the gun (the way that money floats over buildings)

Eta: congrats carewell and letting me know that it was Cletus being free that triggers the build option
