Whether you call it a barrel cover, barrel sock, barrel condom, or barrel sleeve - this item is an essential part of your paintball (or airsoft) safety gear. Regardless of where you play, good safety protocol requires that when you are not on the playing field with your goggles on, then your paintball gun must have a barrel sock in place over the end of your barrel. This device helps keep you and everyone around you safe between games by stopping any misfires from being able to leave the barrel of your paintball or airsoft gun, and potentially causing someone serious harm. Play safely! Always have a barrel sock in place (and keep a spare in your gear bag in case you lose yours, or to share with someone else in your group who needs one to be safe).
