Buy CZ-USA 1020 G2 20 Gauge Semi Auto Shotgun – 4+1 Rounds | 28″ Barrel | 3″ Chamber | Walnut Stock

Breaking records since it’s 2019 introduction, our CZ 1020 shotgun was in need of an American hunting focused feature set. The 2nd Generation (G2) of the gas-less inertia powered CZ 1020 brings to bear the best in a complete package. Instead of redirecting gas from the barrel to run the action, the 1020 series 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 our inertia system is the less stringent maintenance schedule. Unlike gas guns that need periodic cleaning of the piston and magazine tube, our 1020’s needs are vastly fewer. During our testing, we pushed 1020s to 5,000 rounds without a drop of oil or cleaning of any sort, while experiencing zero parts breakage or malfunctions. In normal field use, the occasional cleaning and oiling should be more than enough.

Additionally, the gas-less system itself is tuned to run a wider variety of shells — from light-recoiling target loads up to the smoking hot 3″ magnums currently on the market.
