In addition to the new look, this mechanism has minor changes to both the internal components and the linkages. The rotational precision is absolute, on the order of 2 hundredths of a millimeter, the rotation pins have increased from 4 to 5 mm, the front pin has a double diameter of 4 and 5 mm and acts as a precision spacer. The mechanics are new for 2020. which equips all the mechanisms of the Back series, the shot is more prompt, but at the same time it is softer and more sensitive, the fastening system has been completely redesigned with a new solution, always first to innovate, this new process has allowed us to obtain a bending with the wings in line, and flush with the profile of the rifle, it does not require shims for the adjustment of the fastening which can be done with just 3 screws from above which are hidden thanks to the countersunk holes. The overall design is harmonious and functional, the height of the box is 23 mm, the depth is only 16 mm and the length 48 mm. The width has been changed and reduced from 16.2 mm to just 14.8 mm, therefore the recess to be made less invasive, the shaft attachment component, even after shooting, remains in the profile of the box. This is very important as it allows for a unique recess in the wood perfectly identical to the box. The trigger differs from the old Back series in having a less accentuated saddle, with two different lengths, the shot is more prompt. The line release has been completely redesigned, and moves in a reduced window, but at the same time releases the line perfectly. A spacer roller has been inserted into the line release itself, a unique solution that allows for perfect and precise rotation. The finish, obtained with a special treatment, is steel colored, on request with the Patented Double Roll system.
In this system, friction is reduced to a minimum thanks to two rollers made of hardened 17-4 ph steel, one is placed on the rod coupling component and the other is in contact with the trigger, reducing friction to a minimum.
