I don't have a studio quality camera or place to work so it is what it is. That is a circle Z under the rear sight. A circle B on the stock as well as the underside of the rear sight. There is a circle C on the front sight. A circle K on the left side of the trigger guard as well as the bottom of the receiver. There is a circle L on the bottom of the receiver and on the front of the front band in two different sizes. There is a circle V or A on the back side of the bolt root, I can't tell which one because it's stamped so deeply. There is a mark for the Mexican arsenal that consists of a liberty cap over an oval with F/NA inside that stands for Fabrica Nationale de Armas.
