CZ-USA FIELD SPORTS 712 G3 12Ga 4rd 5 Flush Chokes 28″ Matte Black Chrome Walnut Hunting Shotgun (06167)

Gas-operated semi-automatic shotgun cycles the lightest loads yet handles the recoil from the heaviest shot; The oversized bolt handle makes it easier to operate, especially with gloved hands in colder weather, while an enlarged bolt release facilitates faster reloads; Five Active-Choke Tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full); Active-choke extended choke tubes feature a longer parallel section, delivering the best patterns possible from its .735-inch diameter bore; Extended chokes are easy to change and tighten without tools, so swapping chokes for different target presentations is a breeze; Two interchangeable pistons – for light and medium loads, use the piston with multiple fluted ribs on the body, for heavy loads, use the other piston; Receiver and barrel feature a sturdy matte black finish that reduces glare
