The Axeon Second Zero creates an instant, long range zero. It simplifies target engagement and aim center. It eliminates holdover, guesswork, and range estimation. Extensive ballistic knowledge is not required. Pair the Second Zero with any optic to aim center at long range. When your red dot, ACOG, reflex, or riflescope is zeroed at 100 yards, just flip it in front of your optic and engage your target at the unit's designated range. Just point and click.
