The Ergo-Gapper is designed to fill the small void or gap in front of the pistol grip up to the rear of the trigger guard on an AR-15/M-16 rifle. Falcon Industries' Gapper acts as a cushion and protects the knuckle of the index finger when holding the grip. The Gapper also helps prevent debris from being lodged into the open space and provides a more finished look to the rifle. Falcon Industries produces this part from a solvent-resistant thermoplastic elastomer that remains flexible.
