Dart Zone Pro MK4 – FPS Numbers

We got out hands on a Dart Zone PRO MK4 and have tested every possible barrel and spring combination that comes in the box! (and even with darts that don’t come in the box!).
Below you will find the FPS results with 3 different dart types.

Each setup is tested with at least 20 shots over the chronograph to give you the best performance indication possible.
From each setup we report the highest, lowest and average, as well as the standard deviation.
The standard deviation is an important metric as it shows the consistency between shots, which is important for accuracy.

Please keep in mind this overview is meant as an indication. Dart quality, blaster seals, lubrication, climate and other factors have an effect on performance.
