Why is my front lens off-axis?

Red Dot Lens Positioning: All red dot sights have an objective lens at the front of the unit that is spherical in shape. However, unlike a conventional riflescope, the objective lens in a red dot sight is positioned off axis and appears to be tilted when looking at the sight. This angle of the front lens allows the light generated by the battery powered LED light source inside the unit to be reflected back into the sight. The reflected light becomes the “dot” or aiming reference that the user sees when a red dot sight is switched on. This engineered “bending” of light is what makes today’s red-dot sights so popular and easy to use. Adhesive is used on the inside of the sight to secure the LED to the inside of the tube. By design, the led package intrudes slightly on the field of view.


Recommended zeroing distances?

Most people tend to zero somewhere between 25 and 100 yards. This is really a matter of preference and it is often best to consider what your philosophy of use for the firearm is when you decide on a zeroing distance. For example, someone interested in self defense, might zero at 50 yards or less, while someone looking to do short and long distance range shooting might zero at 100 yards. Seek the advice of a qualified firearms instructor to best understand what zeroing distance is best for you.
