It shoots about 4 meters (13 feet) :D
I measured it to be 17.5 metres (57 feet) but that was shooting at a large angle
The Nerf Switch Shot averages around 25-35 feet per shot with Micro Darts, Whistler Darts, Sonic Micro Darts, Dart Tag Darts and Glow Darts, but very little with Streamline Darts.
They are made, believe it or not, to fire darts at the same speed. The Longstrike doesn't shoot as far because the dart has to travel farther to leave the blaster, which causes unnecessary friction. This is made worse if you attach the barrel.
The soon-to-be newest Nerf blaster, the Sharp Shot, will be the second smallest Dart Tag blaster. It is like the Secret Strike AS-1 of Dart Tag, and should be quite cheap. They have been tested, and so far show promising performance. It should be quite popular when it comes out, but should also be around for a long time so you don't have to immediately get one when it comes out. It fires the new blue-coloured Dart Tag Darts, and looks to be a good blaster.
35 feet
The Nerf nitefinder can shoot up to 36ft (10.80m) without modifications. Trust me, I have done it before.
The Deploy can shoot up to 40 feet if you are lucky.
It can shoot 30 or 35 feet normally.
50 ft
about 30 inches
about 25-30 feet
About 15+ feet.
