Dart Firing Stun Gun Practice Test 2026 - Free Stun Gun Practice Questions and Study Guide

The darts are launched by a burst of compressed gas. When fired, a small amount of compressed gas rapidly expands and pushes a piston that propels the two darts out of the launcher. This is a pneumatic launch system, using gas pressure rather than electricity, springs, or a mechanical lever to push the darts. The electrical components of a TASER come into play after launch, delivering the high-voltage signal through the darts, not in the propulsion itself.
