The MagnetoSpeed V3 ballistic chronograph kit was designed to be used on barrels and suppressors from 1/2 inch all the way up to 2 inches in diameter. In addition to the larger diameter tolerance, the V3 also has one inch more clearance in the blast zone to account for longer (up to 3″ in most cases) muzzle brakes, flash hiders, etc.

Both packages are packed with features and you really should put some thought into which one will work best for your application, the upgraded V3 package is packed with a ton of features that the sporter model just doesn’t have for instance the ability to accommodate larger barrel diameters muzzle brakes and flash hiders.

For our purposes we opted for the V3 for our review a lot of our rifles are of the “Black” variety and we have a range of muzzle devices that we like to use J when I got to the range for testing their was a gentleman next to me using a classic chronograph and I asked him if he wanted to take place in genuine scientific experiment of epic proportions! He said no, and I asked can I use your chronograph for a few minutes and he said sure not a problem (amazing what people will do if you give them a few rounds of free ammo) yes I am not opposed to a little palm greasing in the name of science.

With the first string I shot the V3 gave me very consistent numbers almost to good to be true so I shot 3 more strings to be sure and all of the strings were very consistent. Now I remind you that I also used the classic chronograph at the same time to compare the collected data. See the Table Below:

String One String Two String Three
V3 Brand X V3 Brand X V3 Brand X
Shot 1 3093 3086 3092 0 3094 3081
Shot 2 3090 3087 3091 3011 3091 3078
Shot 3 3090 3091 3091 3080 3092 3063
Shot 4 3088 2988 3090 3075 3092 3059
Shot 5 3091 2997 3091 0 3089 3071
SD 1.82 52.44 0.71 38.48 1.82 9.42
ES 5 89 2 69 3 22
Weapon Barrel Temp Sun Ammo Weight Type
AR-15 16″ 67* Full LC 55 FMJ

As you can see from the data above the V3 gives very consistent reads on the numbers and gives you a very good health report for your ammo. I have spent plenty of time in the past trying to figure out why my chrono results weren’t matching my targets. And with this great new tool from MagnetoSpeed that is a thing of the past, this tool has definitely found a place in the toolbox!

You can purchase from many reputable online retailers including Amazon.
