NOTES FROM LUKE:
While the Dartzone Pro MK2 can't take an upgrade spring due to a maxed out plunger tube system for the barrel length, a low-power spring is a great option for those looking to hit 100FPS or less. This makes playing indoors and at HvZ games easier.
We'll also be offering a sub-130 spring for those wanting to maximize their game-legal HvZ games.
FEATURES:
-Easy spring swap, just three screws to remove the top slide
-100FPS (This will vary depending on your dart selection and dart age)
SPECS:-Material: Zinc-coated spring steel
