So my F1 reticle has always been a little strange. Even though it was leveled definitely with a plumb line, bubble level and tall target tested my dad always swore it was not level. I just thought he was used to holding a rifle canted and dismissed it. Well, yesterday I shot with it and my normal half minute rifle was shooting pretty bad. I also noticed for the first time that the horizontal axis was definitely off. Later at home I set up a target with verified plumb lines. The vertical crosshair is good, but the horizontal axis is most certainly not. I am not sure how the reticles on these scopes are produced but this seems really odd. I bought it from larue so it is not a knock off.
