Sabins Gadgeteering Lab proudly presents its latest design in personal plasma weapon technology, the Alpha-300. With internal lights and sound, it comes with two 12-round magazines of glow-in-the-dark ammo, with the spare in a side carrier attached to the receiver. The semiautomatic weapon uses a motorized flywheel action to feed darts out from the magazine and accelerate them out of the barrel. 4 x AA batteries are included.
Note that operating this weapon requires the flywheels to be brought up to speed for a few seconds before firing, by depressing a secondary switch below the trigger. This also engages UV lights within the magazine well that charge each dart with glowing power.
Here is a video of the weapon firing up a dimly-lit stairwell, to show off the plasma bolts in action.
This device is priced at $75 USD, plus applicable tax and shipping.
