One of the more mainstream attempts at incorporating electronic into firearms technology on the civilian market was the Remington EtronX, introduced in 2000. It consisted of a standard Remington 700 bolt action rifle, with the trigger and firing mechanisms replaced by electric versions. The firing pin itself became an insulated electrode, the trigger operated an electronic switch instead of a mechanical sear, and a 9V battery feeding a capacitor provided the energy to ignite the new type of primer - basically a resistor that would generate heat to ignite a charge of smokeless powder.
Remington made a valiant effort with the EtronX, but came up short. Unfortunately, the only practical advantage to the electronic workings was a reduction in lock time of the action (the delay from trigger press to cartridge ignition). They did in fact achieve a virtual elimination of lock time, but this was not a problem that needed to be addressed for the general sporting rifle market. Between questions about ammunition availability and a general market rejection of electronic component in firearms, the rifle failed to sell, and was dropped from Remington’s catalog in 2003.
