Freak Aluminium Insert
Changes in temperature and humidity cause paintballs to shrink or swell. The Freak and Freak Junior are the only barrel systems that match paint size by utilizing inter-changeable sized aluminium inserts. There are 9 different sizes and each size has its own colour for easy identification. The insert sits inside the back piece of the barrel.
Better gas efficiency
Decreased chance of breaking paintballs
Freak inserts can only be used in The Freak back or Freak Junior back
