Design and Performance

Here is what NAP states on their website about the Thunderhead:

Patented micro grooved ferrule greatly increases flight accuracy and penetration power. No other broadhead in the world flies as true as the Thundherhead, period.

We found reports of customers saying that they were not happy with the O-Ring fitting. And if you plan to use these on carbon arrows, you should also purchase the UBARs (universal broadband adapter rings).

To ensure that they spin true you should put an arrow spinner to use. This is due to the rubber gasket

The three blade design ensures the effectiveness and stability you will learn to love.
