Abstract
The present invention relates to an extension barrel, which comprises an outer tube and a dye coating module. The outer tube is provided at the rear end thereof with a connector portion adapted for connection to a front end of a pneumatic gun. The dye coating module is mounted within the outer tube, so that a bullet projected from the pneumatic gun is coated with dye having a desired color when passing through the dye coating module. As a result, the object hit by the bullet is stained with the color and can be easily identified.
