MagnetoSpeedTapered Spacer Kit, Orange

I purchased these tapered shims in case I needed these for different barrel's. Good investment in case you need them. In my case, for the rifle I'm setting up, I did not need them but, I have them if I need them for another rifle.

I was disappointed that this was not included with the Magnetospeed unit as a large percentage of rifle barrels are tapered. But, the price of these was low enough that I can live with having to buy them separately. They appear to space the sensor more than the maximum recommended by Magneto, but I have had 100% success with getting readings.

They work exactly as expected - add the appropriate shim amount to your MagnetoSpeed. Likely should be provided with each as most barrels are tapered anyways.I gave it 4 stars as the shim degree amount could be labeled but it was not - otherwise 5 stars.I used on my Daniel Defense MK12 that has a slight taper at the tip instead of a straight barrel - worked perfect.

Like others said it should have came with. Can't wait till the sun comes up to test them out. I have a few rifles with a tapered barrel that I was always scared to use the magneto speed on. Defintly worth getting.

Good product, but ended up not needing them. My Browning BAR Mark III has a tapered barrel, so thought these would be needed. However after installing them on my chronograph, it was angled badly. Calipers showed my barrel taper ends about 8" from the muzzle, though visually it appears to continue all the way.
