Nothing can ruin a game of paintball like a broken paintball in a barrel, ruining accuracy and often leading to missed shots that could have made all the difference in a game. Quickly clean a barrel of broken paint and shell and get back to the business of shooting accurately with a barrel swab! The Valken .50 caliber barrel swab quickly restores accuracy on and off the field, and folds in two for easy storage in a pouch, pocket or squeegee pouch on paintball pants! Double ended for deep cleaning.
