The 330-yard model seems like it boxes you into that range, but of course, there is some leeway. With the Axeon Second Zero equipped, I ensured my 100-yard zero was dead-on and then walked back another 200 yards. I did the same thing for the Second Zero by raising it and lowering it to see how accurate the supposed 4.3 MOA reticle adjustment is.īelieve it or not, it was dead on like scary accurate at exactly 4.3 MOA. 5 MOA adjustment value, you test to see if that is correct. This measures how accurate your scope adjustments are. When reviewing optics, or just testing them, there is something known as a scope tracking test. It’s quite simple and seems to lock up exceptionally well. It pops up and goes down with the flip of a lever. The Axeon Second Zero system installs quickly enough, and it can be placed pretty much anywhere in front of the optic. Once I understood how it works, I shifted my thinking from its snake oil to seeing something special. The shift creates an automatic holdover based on a 100 yard zero. Essentially once the lens is in place, your reticle is adjusted upwards. With the 330 yard model, the angle is 4.3 minutes, and with the 530-yard model, the angle is 11.5 minutes. It’s a prismatic lens that deflects incoming light at different angles. The Axeon Second Zero is a simple system. They are unintrusive and get out of the way when you don’t need them. The scope mounted models flip upwards when it’s not needed. The rail-mounted model folds down and out of the way when it’s not required. With the rail-mounted Second Zero, you’ll need roughly an AR height sight to use the optic properly. In theory, the Second Zero would give you an instant holdover. Longer range shots with a red dot typically require you to apply some guesswork for bullet drop. In front of a red dot, this could be incredibly handy for taking long-range shots. I tossed mine in front of a 3X prism optic from Swampfox.
