The latest evolution in our 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 shotguns recoil, spending this energy a split second later to rotate and unlock the twin lugs from the barrel extension and withdraw the spent shell. Additionally, the gas-less system itself is tuned to run a wider variety of shells from light-recoiling target loads up to the 3″ magnums currently on the market. We’ve actively searched out the shells that it doesn’t like to cycle, and so far the limit on too light is the Winchester Featherlite (23/25 oz at 980 fps) and too hot is Remington HyperSonic (1 1/4 oz at 1700 fps). That means the 1012 will readily digest the vast majority of shotshells on the market. Features a 8mm flat vent rib with a 14 1/2″ length of pull.
