Variable velocity rifle turns from lethal to non-lethal

Sometimes, you want a gun with the power to kill someone. Other times, you want a gun that'll just get them to stop making all that noise while you're trying to sleep. The Lund Variable Velocity Weapons System gives you both options in one convenient rifle.

It does this with variable velocities, allowing you to select low velocity for non-lethal use and high velocity for lethal use. And since if you're close enough even low velocity could kill someone, it also has a safety system on board to prevent close-range firing. Perfect! I'll take three.
