Unlike a regular spring, a torsion spring is powered by "torsion", or twisting power. When the blaster is primed, the spring is twisted around in a spiral or coil. Its energy is released when the spring untwists, and does not rely on air seals or a plunger. The torsion springs within a Vortex blaster are helical torsion springs.
When a blaster with a torsion spring is primed, it tightens the coils of the spring. When the firing trigger is pulled, the spring is released and snaps forward, flinging the XLR Disc or High-Impact Round out of the barrel.
Torsion springs were first used on the 2011 Vortex line.
Torsion springs were revisited again in RIVAL blasters, however, these torsion springs are used in addition to a direct plunger.
