Boost the performance of your Empire Axe and Mini and Battle Tested TM7 and TM15 with the TechT High Performance Spring Kit. Reduce your paintball guns operating pressure and dwell by using different tensioned springs from this kit to achieve the best performance fit for your specific marker. Spend less time at the air station and more time shooting up the field with your newly improved and efficient marker.

• You can use these springs in the Phenom, but they can allow the bolt to operate at a very low, very efficient pressure, that is sometimes to low to operate the cyclone feed. Use with a Phaze 5, or just the Phaze 5 instead.
