Here's how the Model 700 EtronX works: The electronic fire control has no moving parts other than the trigger. No sear to be released. No firing pin to strike the primer. Instead, an internal electrical circuit sends a charge through the system to our new electrically responsive primer. Closing the bolt on the cartridge establishes contact between the firing pin and the primer. When the trigger is pulled, the electronic circuit sends an electrical pulse through the firing pin directly to the primer. This all happens in less than the blink of an eye. Ignition is even faster, with near zero lock time (.0000027 seconds, actually), which virtually eliminates the effects of barrel movement after pulling the trigger. In fact, the bullet exits the barrel of the Model 700 EtronX before a mechanical firing pin could even hit the primer in a conventional rifle. The system also creates an exceptionally crisp trigger pull with 36% less travel than standard triggers.
