NO. Byrna Less-Lethal Self-Defense Pistols and Rifles are powered by compressed CO2 cartridges, just like a paintball or airsoft gun.

The Byrna EP,SD, and LE are compact non-lethal personal security devices developed by Byrna Technologies Inc. NASDAQ:BYRN. The Byrna launchers fire a .68 caliber projectile that is cross platform compatible. The Byran are manufactured from the highest quality of glass-reinforced polymers and aircraft grade aluminum. They contain more that 100 precision parts, and have patented technologies that allow Byrna to operate very much like a real firearm.
