CZ 1012 28in 12 Gauge Synthetic Black Semi-Auto Shotgun (06351)

The CZ 1012 semi-automatic shotgun 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.

The major advantage of an inertia system is the less stringent maintenance schedule. Unlike gas guns that need periodic cleaning of the piston and magazine tube, the 1012's needs are vastly fewer. In normal field use, the occasional cleaning and oiling should be more than enough.
