Support structure for optics applicable to a rifle and related assembly

A support structure for optics adapted for application to rifles a rifle, the latter rifle comprising a butt, at least one barrel extending along a longitudinal axis, a magazine assembly, and a trigger, wherein said magazine assembly is constrained to the remaining parts of the rifle at two or more constraint points, through one or more fastening members located upstream and downstream of said trigger with reference to said longitudinal axis;

• said support structure comprising:
• a positioning portion adapted to support and constrain an optics unit;
• a constraining portion adapted to constrain said support structure to the rifle;
• a body adapted to mutually connect said positioning portion and said constraining portion;
• wherein said constraining portion comprises at least two constraint elements;
• said two constraint elements being adapted to be positioned at said constraint points located upstream and downstream of said trigger, and being adapted to be constrained to said rifle by two or more fastening members, which constrain said magazine assembly to said rifle at said constraint points.
