|There's no category just for Props, so it's here.|
One of the iconic weapons from Team Fortress 2 is Sasha, the Heavy's minigun.
Many people have made Sasha props, usually have made them to spin the barrel.
However, none of them actually shoot bullets. which is why I built mine with a Nerf 'Vulcan/Havoc Fire' so i can launch nerf darts at my foes.
