How to Zero With Iron Sights | Shooting Techniques | Tactical Rifleman
This guide details how to zero iron sights on AR-style rifles, including the M4 Carbine, as demonstrated by Karl Erickson, a former US Special Forces operator. It covers selecting zero distances (25m for 300m equivalent, 50m for 200m equivalent), proper sight configuration, stable shooting positions, and calculating/applying windage and elevation adjustments using the front sight post and rear sight knob. The process emphasizes confirming zero at both short and long ranges.
