The 712 series utilizes gas-operated piston to ensure smooth and reliable cycling and utilizes a 3-inch chamber compatible with 2.75-inch shells that allows it to accommodate a wide variety of loads. Updates to the G3 include the inclusion of interchangeable pistons and an oversized safety located at the front of the trigger guard for more natural manipulation.

This model is chambered in 20 gauge and features a Turkish walnut stock, a matte black finish, and a 26-inch barrel. Five CZ Active Extended chokes are included (F, IM, M, IC, C) along with two pistons for light and heavy loads and a lockable hard case.
