The typical stun gun can put out 20,000 to 150,000 volts. What matters is how long someone is exposed to it. As for fire rate an M16 can fire up to 16 rounds per second (keep in mind this is in top working condition and when all parts are cool, same as the 24 rounds per second for Valkou). A chain gun can fire between 34 and 100 rounds per second depending on how cool the parts are and what condition every thing is in. Valkou sits (at it's prime) somewhere between a chain gun and an M16 in both firing rate and accuracy.
