To get the most out of your markers a TechT MRT Spring Kit is essential! The TechT MRT Spring Kit provides players with three distinct levels of resistance which will allow for lower operating pressure, as well as reduced dwell times.
This means better efficiency = more time on the field, rather than the fill station.
