It't not "magic", but the concept behind the Etronx is that without a firing pin and moving mechanical parts, except the trigger, there is less motion and therefore more accuracy, it uses an electirical charge (if you didn't read the web page).I don't know how much accuracy you would gain but it would be interesting to see a review of it. It is an interesting idea, but I don't know how accurate it is compared to traditional rifles but it is an interesting idea non the less. It would been an interesting rifle to test but it does cost quite a bit.
