Evo-Back

.Derived from the Back Mechanism, it differs only by a plate welded on the front of the roof of the box, this allows you to have the 3 fixing points in line on the same plane, the advantage is to be able to have a greater quantity of wood, in the point of greatest stress , and therefore a greater robustness of the rifle. .Mechanism with patented system, operation with two rollers, one works in contact with the trigger and is constrained to the coupling lever, the second roller in contact with the shaft is constrained to the box with a pin and is free to move in an oval hole , this system stabilizes the shaft at the moment of firing, the load is evenly distributed decreasing and practically eliminating friction. .The line release  interacts with the coupling lever of the shaft with a system that all manufacturers have now recognized as the best system, and adopted worldwide. We are the inventors of this innovation, just as we were the first to adopt rotation fulcrums suitable for decr
