So you have a cool looking Gel Ball Blaster but realise that it doesn't shoot that accurately when you are playing with your friends. Then you need to check this out. This brass barrel replaces the 2 piece plastic inner barrel pieces to give you consistent shots and more range than stock.
 
The brass barrel is slightly longer than stock so you may find that it slightly sticks out of the front rail.
 
You can go back to the stock plastic inner barrel as the change isn't destructive!
 
NOTE - Using newly hydrated gel balls in this may cause 'shotgunning' or dry firing due to the tighter ID tolerances compared to the stock tube.
