A firearm can have a handguard having an inner section and an outer section with the outer section having circuitry and control devices for controlling electronic devices. The electronic devices can be part of the outer section. The inner section attaches to the firearm similarly to a current art handguard. The outer section attaches to the inner section. Different functionality can be obtained through the attachment of different outer sections to the inner section. The outer section can obtain electrical power from a power supply attached to or integrated with the firearm. The outer section can alternatively receive electrical power from a power supply carried by a person in a back pack or vest.
