The Browning A5 makes better use of kinetic energy with its powerful, short recoil-operated Kinematic Drive System. Kinematic Drive harnesses recoil energy and converts it into the mechanical motion needed to operate the action. The Lightning Style stock with its semi-pistol grip design is noted by the rounded knob at the bottom of the grip. The relaxed grip angle offers a quick, instinctive grasp and easy reach to the trigger, making it ideal for fast-flushing upland birds. The humpback receiver profile long sighting plane will give you the same sighting advantage the first Auto 5s were famous for. Includes three chokes and T-wrench.
