Keep you paintball gun Cronoed under 260 FPS when using Grippers.
-GREAT FOR PEOPLE WHO WORK ON THERE OWN EQUIPMENT AND NEED TO TEST FIRE!
and, oops, they even called them 'v-balls' which is a name of another company if I'm not wrong http://vballs.com/They will chrono slightly slower than a normal paintball do to the mass. You will be AMAZED how accurate Grippers perform.
What if the VBalls get dirty or full of paint?
VBalls are washable! Just throw them in the washing machine with a bit of soap on the short cycle and they will come out clean as a whistle.
