The CZ 712/720 is a gas operated semi-automatic shotgun built on a light weight alloy receiver. Both the 26" and 28" barrel configurations accept the 2 3/4" to 3" shells, making the new shotgun a great choice for both upland game and waterfowl. The barrel on the 712/720 is chrome lined with a moly black hard chrome exterior finish that wil resist corrosion after many seasons in the field. It is fit with a Turkish walnut soick sized for a 14.5" length of pull. The 712/720 comes with a magazine tube plug installed for waterfoul. If the plug is removed, it gives the upland hunter a 4+1 capacity.
