The AR-15 BCM gunfighter KAG (Kinesthetic Angled Grip) is the end result of a collaboration between BCM and Travis Haley, who is an inventor of multiple weapons manipulation enhancements in the firearms industry. This device is designed to complement modern shooting grips and the KAG specifically uses a biomechanically efficient forward rake to create an interface for positive retention and joint relef to the wrist, elbow and shoulder.
