Uzi

The Uzi is a gun with a high rate of fire and a high damage output. Musket Balls and Silver Bullets shot from this weapon gain the effects (but not damage) of High Velocity Bullets. It has a 0.5% chance to drop from the Angry Trapper.

Trivia

 * The Uzi, Musket, Shotgun and the Red Ryder are the only three specifically named real-life firearms in Terraria.
