Magnetospeed V3 Chassis Mount

Measure every shot with the Magnetospeed V3 chronograph without distracting the harmonics of your rifle system. Altough a lot of people claim that there is no point of impact (POI) shift when mounting the Magnetospeed, that is not what we experienced. With thinner contoured barrels we noticed a change in POI of as much as .3 mil (vertical) and .1 mil (horizontal). By mounting the chronograph an the chassis rather than the barrel, we eliminate all that mess permanently.
