Combination Forward Grip and Stabilizer

A novel forward grip combines the advantages of a forward grip with the stabilization capabilities of a bi-pod into a single shooting accessory for the modern tactical law enforcement or military operator. When the grip is used to stabilize the fore end of the weapon, it prevents the weapon from slipping and sliding due to recoil. The grip also provides relief to the shooter's grip while under stress by compressing and conforming to the shooter's hand. Reduction of the movement of the shooter's sight picture is also provided by reducing the negative effects from weapon recoil. The grip includes a primary finger grip located on the outer perimeter of the grip to allow shooters with large hands to grip the rifle. A secondary finger grip pocket is also provided in the interior section to conform better for shooters with smaller hands. The grip is made from flexible rubber to allow it to conform to against a wide variety of shapes to provide a stable shooting platform without the need to change out to a bi-pod. The secondary finger grip may also be used to hang the rifle on a post when not in use. The grip may be mounted to the standard Picatinny rail and includes two hard locking points. The grip not only stabilizes the weapon's fore end, eliminating the need for a bi-pod, but also conforms to difficult shooting platforms that prior art hard plastic forward grips cannot accommodate.
