CZ 1012, Semi-automatic, 12 Gauge, 3 Chamber, 28 Chrome Lined Barrel, Matte Finish, Bronze Receiver and Black Barrel, Wood Stock, 4 Rounds 06353
The latest evolution in CZ's semi-automatic shotgun line" the 1012 uses a gas-less inertia operating system. Instead of redirecting gas from the barrel to run the action" the 1012 uses a spring within the bolt to store energy during the shotgun's recoil" spending this energy a split second later to rotate and unlock the twin lugs from the barrel extension and withdraw the spent shell.
