The Empire Super Freak Paintball Barrel Kit is an eight piece barrel kit that will allow you to match the size of the paintball to the barrel. Paintballs vary in size between manufacturers and choosing the correct size is very important when you want accuracy. The Empire Super Freak consists of a front section (tip), a back section (back) and five color coded aluminum inserts. The inserts are interchangeable and allow the perfect fit to the paintball you are using. The threaded sections of the Super Freak have an o-ring to prevent the barrel from vibrating loose when fired. There are also two o-rings within the barrel back to keep the insert from sliding out of the barrel. All of the Super Freak's parts come with a deluxe storage bag that you can put into your gear bag and keep things organized.
