EMPTY CHAMBER INDICATORS (ECIs) WITH MT. WASHINGTON’S LOGO

An Empty Chamber Indicator or “ECI” (sometimes referred to as an Open Bolt Indicator or “OBI”) is a plastic device which is inserted into the chamber of a firearm to clearly indicate that the firearm is not loaded and the bolt is open. These devices are required under AGC’s Range Rules. They are available for a nominal cost at our Club meetings and events.
