Power test comparison without and with valve block HDR50 T4E revolver

In this video I try to answer one of the most common questions - what is the power difference between a revolver with a valve block and a revolver without a valve block.
In this video, I check the power of a brand new Umarex HDR 50 t4e revolver with a valve block mounted with and the same revolver without a valve block.
The HDR revolver is available without permission and is used for entertainment and self-defense. As ammunition, you can use rubber balls, rubber-steel balls and balls made of other plastics, glue etc.
For the test, I use steel-rubber balls and a Devastator, the measurement is made with the X-Radar chronometer.
