This is not just another barrel cover. Empire has done it again with another innovative idea to make your paintball life easier. Your barrel cover is there for one reason and that is to protect you from an accidental misfire. BUT how annoying is it when you DO shoot the inside of your barrel cover and paint is everywhere inside there...it is next to impossible to clean the inside of those things. They have developed a ballistic nylon liner that can be pulled out with a bungee loop rip-cord to be easily cleaned so you can go back to covering your barrel clean and get back into the games.
