The heart of the Epiphany is a paintball first – an adjustable volume fire chamber. Color-coded inserts are used to alter the amount of gas the Epiphany stores in its fire chamber. This flexibility allows the Epiphany fire chamber volume to be reduced while maintaining full velocity. With a smaller fire chamber, the Epiphany valve can recharge faster, protecting it from shoot-down or undesired velocity fluctuations when the player is shooting at 15 balls per second or more.
