The innovative minds at Axeon Optics have created the simplest way to accurately zero in your scope with a single shot. Two red precision lasers ensure you are holding your rifle stable and in the same position as your previous shot, eliminating holding error. Using this sight-in modular is easy to use saving you time and ammo by only requiring a single shot fired. Simply place the included laser grid over your intended target at 25 yards and make a note of your lasers location on the grid. After firing your first shot, put the lasers back on the grid where they were originally located before you fired and move your scope reticle to the point of impact. Your rifle scope or sight is now 100% sighted in at 25 yards, letting you focus more on the task at hand. If you are aware of how much your ammo rises or falls over the span of 100 yards you can use that calculation to make an accurate adjustment on your scope for longer range shots. Two different mounting platforms come are included in every package to ensure the perfect fitting on any rifle. The Absolute Zero is a favorite among hunters and airsoft enthusiasts alike as they do not need to give anyway their position just to make sure their scope is sighted in properly. Revolutionize the way you way you zero in your scope with the new Absolute Zero Red Laser Sight-In from Axeon Optics.
