UK Legal & Site Notes
As an internal mosfet, the MDRX V3 doesn’t alter your rifle’s external appearance or FPS output. However, always programme your ECU’s settings to comply with your local site’s chronograph limits before play. Most sites recognise DMR settings once you’ve demonstrated compliance.
