Currently, assault rifle grips are fixed at a specific angle, primarily based on the ability to fire a rifle with the center of mass aligned to the forearm, with little to no wrist movement. The grip angle best accommodates shooting from the hip and a traditional bladed rifle stance. Tactical shooting has led to the development of a squared, or athletic, stance. With the squared stance, the shooter’s shoulders are squared-up with the target, the buttstock of the rifle is near the centerline of the body and high up on the chest, and elbows are kept down and tucked in. With current rifle grips, this stance results in ulnar deviation of the wrist causing wrist fatigue and injury. Naval Surface Warfare Center, Crane Division, has designed, developed, and patented an adjustable ergonomic rifle grip that allows the grip angle to be modified to accommodate different shooting stances. By rotating the grip, wrist fatigue and injury can be minimized by allowing the shooter to hold the weapon at, or closer to, the natural wrist position. Additionally, the rotatable grip can be folded up to the body of the firearm to make it more compact for concealment or storage.
